ownCloud Server 10.3.1 is a bug fix and maintenance follow-up release. You can read the full ownCloud Server changelog for further details on what has changed. It is recommended to schedule an upgrade to this version soon.
Apart from this patch release, please consider the ownCloud Server 10.3.0 release notes, below.
Dear ownCloud administrator, please find, below, the changes and known issues in ownCloud Server 10.3 that need your attention. You can also read the full ownCloud Server changelog for further details on what has changed.
For improved compliance with the OpenCloudMesh protocol specification (Federation) a migration step will convert the fields of the
remoteIdcolumn of the
string. This migration might increase the upgrade duration depending on the number of federated shares.
A repair step has been added that drops the deprecated
contacts_cards_propertiestable. This migration is not expected to increase the upgrade duration significantly.
A housekeeping repair step for the
oc_propertiestable removes existing entries which have
nulland restrict the further creation of such. This repair step is not expected to increase the upgrade duration significantly.
ownCloud Server 10.3 officially supports PHP 7.3. The Server Core and all apps maintained by ownCloud have received a full QA cycle and are proven to work reliably with PHP 7.3. If you are still using version 5.6, you must upgrade PHP before upgrading ownCloud Server as it’s not supported anymore since ownCloud Server 10.2. If you are still running PHP 7.0 or 7.1, please plan an upgrade soon as these versions are or will soon be unsupported, respectively. See the system requirements in the ownCloud Documentation for more information.
For code cleanup reasons, the execution of background jobs (e.g., for public link expiration, trash bin emptying, cleanup of old file versions) has been changed.
The following changes require manual interaction in your installation:
If you’re using System cron to trigger background job execution, there is a new
occ system:cron) which executes the background jobs. To make use of it, you have to change the entry in
crontab. Instead of executing
/usr/bin/php -f /path/to/your/owncloud/cron.php), cron should use
sudo -u www-data php occ system:cron). As a fallback,
cron.phpwill continue to work with Server 10.3 but will be removed in a later version.
If you’re using Webcron to trigger background job execution you now have to call the new route
../cron.php. As a fallback,
../cron.phpwill continue to work with Server 10.3 but will be removed in a later version.
|See the occ System documentation for more information.|
In a later version of ownCloud Server,
|If your ownCloud deployment is based on the official Docker images or the Univention appliance, these changes have already been applied for you.|
The Media Viewer app has recently been released.
The Media Viewer is the next generation image and video file viewer for ownCloud.
It provides a foundation based on new technologies and officially supersedes the former
ownCloud Server 10.3 does not bundle
Instead, it bundles
With this change, support and maintenance for
files_videoplayer are discontinued.
More details on the Media Viewer can be found in the release blog post.
For a clean transition to Media Viewer, it is necessary to disable both deprecated apps before the upgrade using either the admin "Apps" panel in the web interface or via
occ app:disable galleryfollowed by
occ app:disable files_videoplayer).
After the upgrade, enable the Media Viewer app via the admin panel or
occ app:enable files_mediaviewer.
It is not recommended to continue with the deprecated apps. However, if you want to do so, you can copy over the
files_videoplayerdirectory from the
apps/folder of the previous ownCloud Server directory and obtain
galleryfrom the ownCloud Marketplace.
Please do not enable
For more information on the Media Viewer app, visit the ownCloud Documentation.
Server 10.3 comes with improvements for session handling with Redis. These are designed to cope with issues encountered around duplicate session tokens, which make the ownCloud Clients lose their OAuth2 authorization from time to time, and force users to re-authenticate.
The session handling in ownCloud 10.3.0 has been generally improved, making user and client sessions more stable. If Redis is used for session handling, it is necessary to enable Session Locking to ensure that the mentioned issues no longer occur.
You can find out if Redis session handling is configured in your web server if you generate an ownCloud Configreport in the web interface. You will find the value
It is recommended to use Redis Session Locking if Redis is used for session handling (minimum required version for
Enable Redis Session Locking by setting
redis.session.locking_enabled = 1in
|If Redis is just used as a memory cache or not in use at all, you do not have to apply changes.|
|Please note that Redis Session Locking is not supported in clustered Redis environments.|
|If your ownCloud deployment is based on the official Docker images or the Univention appliance, you do not have to apply changes as Redis is not used for session handling (unless you configured it differently using ENV variables).|
To cope for long user names or additional user information and to provide a better overview for users, the user/group sharing autocompletion dropdown has been restructured. The available information is now distributed vertically to improve space usage and user experience. Screenshots are available in the pull request. Other ownCloud clients will align with this behavior with the next releases.
Following the deprecation announcement with ownCloud Server 10.0.9, support for primary and secondary storage via the OpenStack SWIFT protocol has been removed. Please get in contact with ownCloud Support if you’re still using OpenStack SWIFT and want to upgrade.
The extension to integrate S3 object storages as secondary storages (
files_external_s3) has been updated, unbundled from ownCloud Server (was previously part of
files_external) and released to the ownCloud Marketplace.
If you’re using S3 external storage mounts, you have to conduct some steps to ensure continuous operation after upgrading to Server 10.3:
After the upgrade to Server 10.3 has finished successfully, keep the maintenance mode activated and install/enable
files_external_s3(either manually or via the Market app) as the app is not bundled with ownCloud Server anymore.
If users were allowed to configure personal mount points before the upgrade, switch from maintenance mode into single user mode (
occ maintenance:singleuser --on) and enable the option again by ticking the respective checkbox (Amazon S3) below "Allow users to mount external storage" (in Admin settings ⇒ Storage).
Existing storage mount points will remain and do not have to be touched.
Make sure that everything works and disable maintenance/single-user mode to put the installation back into normal operations (
occ maintance:mode --off/
occ maintenance:singleuser --off).
ownCloud Server is being prepared for Phoenix, the upcoming web frontend for ownCloud. As Phoenix is separated from the backend and communicates only via HTTP APIs, it is necessary to complete the API coverage.
The following new HTTP APIs have been added with Server 10.3:
All new endpoints are currently in tech preview state and are mainly used for Phoenix development.
For this reason, they are disabled by default and have to be explicitly enabled using the new config.php option:
'dav.enable.tech_preview' ⇒ true,.
previews_pathconfig option has been added to allow customization of the thumbnail storage path (by default those reside in the user storage). #35131
An Activity entry is now shown when a share receiver unshares a share. #35193
The config.php options
proxyuserpwdwill now be respected to enable federation when an instance needs to go through an authenticated proxy to reach a federated instance. See
config.sample.phpand the Federated Cloud Sharing Configuration documentation for more information.
occ files:scancommand is now case-insensitive for the userid. #35324
dav.enable.tech_preview) has been added to disable tech preview APIs by default. #36124
[PHOENIX] Support for redirecting links to ownCloud Phoenix frontend has been added by introducing a new
config.phpoption which stores the address where Phoenix is reachable (e.g.,
'phoenix.baseUrl' ⇒ 'http://phoenix.example.tld:port'). #35819
The performance when loading groups of users has been improved. #35822
Memory handling for the trashbin expiry background job has been improved. #35708
A new occ command,
encryption:fix-encrypted-version, has been introduced to address issues related to encrypted files no longer being accessible. This originated from a security measure to avoid that encrypted files with the same content look identical. In some cases, users get a
Bad Signatureerror when trying to access files. The new command corrects this behavior, making files accessible again. The command only needs to be run if users report the mentioned error. #115
If an instance uses the
share_folderconfig.php option to gather incoming user shares in a specific folder, this folder cannot be deleted by users anymore. #35998
config.phpoption now also respects federated shares. #35396
user.min_search_lengthconfig.php option now also respects federated users. #35977
Issues with database conversions using the
db:convert-typeocc command (e.g., SQLite to MySQL) have been fixed. This is still in an experimental state and should be tested thoroughly. Please provide feedback if you encounter issues. #35390
File integrity checking has been improved to prevent issues: If a checksum mismatch occurs after uploading a file, the uploaded file and its checksum is deleted to prepare for a clean re-upload. #35294
User/group sharing permission handling
When a share recipient shared a resource with a group the resource owner was a member of (reshare), the resource owner was unable to increase the permissions of the initial share. This has now been fixed. #35884
When a user shared a resource with a group, share recipients (members of the group) were able to remove the share altogether (instead of just unsharing from themselves). This has been fixed. #36120
External storages now return
StorageNotAvailablecorrectly on temporary network failures to prevent associated issues (e.g., Desktop clients will not delete local folders anymore when the storage is temporarily not available). #35707
External storage: Multiple Google Drive external storages can be added again. #34987
The input fields in user administration are not captured by password manager autocompletion anymore. #35931
Storage encryption with a master key in an HSM: Recreating a master key works again. #128
Tech preview for OCS API for public link share email notifications (disabled by default). #36063
Tech preview DAV endpoint for public shares (disabled by default). #35932
Two-factor providers may now display custom challenge messages. #34848
The theming capabilities have been improved by allowing HTML for
LogoClaim. Please check the changes to owncloud/theme-example if you are interested in making use of this in your theme. #35273
A new Roles API has been added to allow clients to query the server for available permissions/roles for user/group sharing and public links. In future client releases, this endpoint will be used to dynamically display roles/permissions depending on the server’s capabilities. You can find out more about it in the Roles API documentation.
|This section will be updated if further issues become known.|
WebDAV Locks: When a file in a folder is locked, exclusively locking the parent folder currently still works ("conflicting lock"; divergent from RFC 4918))
ownCloud Server 10.2.1 is a bug fix and maintenance release taking care of several bugs and known issues. Please find, below, the changes in ownCloud Server 10.2.1 that need your attention. You can also read the full ownCloud Server changelog for further details on what has changed. It is recommended to schedule an upgrade to this version soon, especially if you’re running 10.2.0 already.
|No occ upgrade is required when upgrading from 10.2.0.|
ownCloud Server offers two ways for key management with storage encryption.
Either a central master key pair or individual user key pairs are used to encrypt/decrypt data.
Previously both modes used the same mechanisms which resulted in potentially significant overhead when master key encryption was used as user key encryption relies on so-called
share keys which are necessary to allow share recipients to decrypt shared files.
With master key encryption,
share keys are redundant as you have one central key that can be used to decrypt all files.
Version 10.2.1 corrects this behavior by dropping
share keys for master key encryption, thereby increasing the performance dramatically, especially when sharing folders with many files as said keys do not have to be generated anymore for each file.
Fixed reshare permission issue
An issue in the Sharing API allowed users to increase sharing permissions beyond their own permissions in a reshare scenario: When user A shares a folder "Project" with user B, granting only read and share permission, then the Sharing API allowed user B to reshare a subfolder of "Project" with user C granting full permissions or to create a public link on the shared folder, respectively. This undesired behavior is fixed with 10.2.1.
Fixed issue with Sharing API and enforced public link expiration dates
An issue in the Sharing API caused the ownCloud clients to prevent users from creating public links when the option "Enforce expiration date" for public links is in use. This is now solved.
Fixed known issue with user avatar paths
Version 10.2.0 accidentally changed the location of user avatars making them unavailable and storing uploaded avatar images in the wrong location. 10.2.1 restores the earlier behavior and provides a repair step to move back the avatar images uploaded with 10.2.0 to the right location. As it is not necessary nor possible to run
occ upgradewhen upgrading from 10.2.0 to this patch release, if you are already running 10.2.0 then after installing 10.2.1 you need to run
occ maintenance:repair -s 'OC\Repair\MoveAvatarIntoSubFolder'manually to trigger the repair step.
Fixed known issue with "Password changed" HTML emails rendered in plain text
Fixed use of invalid token on password reset
Password reset links sent to a user were invalid, if the user attempted to login using their e-mail address and an invalid password prior to filling out and submitting the Reset Password form.
Fixed issue when removing a user from a group
Removing a user from a group using the user management UI resulted in an error that required the page to be refreshed to show the changes. This has been corrected.
Added -y option to
The occ command
encryption:encrypt-allnow offers a
-yoption that can be used to automatically answer potential questions with "yes" which is particularly important for automated deployments with Ansible or similar tools.
Fixed an issue with loading JS files when multiple apps folders are in use
Previously ownCloud would have taken the files from the
apps/folder even though there might be newer versions in e.g.
apps-external. This has been changed so that ownCloud will always take the files from the most recent app version.
|Apart from this patch release, please consider the ownCloud Server 10.2.0 release notes.|
Dear ownCloud administrator, please find, below, the changes and known issues in ownCloud Server 10.2 that need your attention. You can also read the full ownCloud Server changelog for further details on what has changed.
Please note that this minor release contains database migrations which impact the upgrade duration. Specifically:
oc_sharetable has a new column. The time the upgrade takes for this change depends on the number of shares in your ownCloud installation.
oc_authtokentable’s login name column size has been increased. The time the upgrade takes for this change depends on the number of recently logged in users, and the number of app passwords that have been created.
Following up the PHP 5.6/7.0 deprecation notice in the ownCloud Server 10.0.8 releases ownCloud Server 10.2 does not support PHP 5.6 and some apps no longer support older PHP versions. Additionally, PHP 7.3 support will be available in an upcoming version.
If you’re still running PHP 5.6, you must upgrade to PHP 7 before upgrading to ownCloud Server 10.2. Please be aware that apps that do not support outdated PHP versions will not upgrade.
To allow for additional upgrade time, version 10.2 still supports PHP 7.0, because some of the major Linux distributions continue to support it. However, support for PHP 7.0 will be discontinued in an upcoming version of ownCloud 10, to enhance both security and performance. To prepare for this change, we strongly encourage you to begin planning an upgrade as soon as possible.
The new server version introduces the means for extensions to implement additional, advanced permissions for user and group sharing. This feature increases sharing flexibility and opens the doors for extension developers to introduce new functionality based on sharing permissions.
Especially, considering collaborative editing solutions, this addition provides the foundation for mode-based document sharing, such as "view-only", "comments-only" or "enforce change tracking". In the future, such advanced permissions should significantly improve the security as well as the usability of review processes, working on Office documents collaboratively, or exchanging information securely.
Based on the new capabilities a set of features has been developed together with Collabora Online, called Secure View. Secure View is designed to enable information distribution processes for sensitive data, meaning that information can be provided securely yet can — under no circumstances — leave the platform.
Practically, it enables users to share documents (such as docx, xlsx, pptx, and PDF files) in such a way that the recipient can’t edit, download, copy and paste, nor print them. Additional protection for screenshots and photos is provided by watermarks which display user information. What’s more, users can decide to allow printing and exporting of documents protected by watermarks as well.
With ownCloud Server 10.2, the former "Download / View / Upload" permission has been renamed to "Download / View / Edit", as this better reflects its behavior (full permissions). Additionally, a new permission ("Download / View / Upload") has been introduced which allows recipients to view, download, and upload contents but not to make any changes to existing content (e.g., rename, move, delete, update). Another way of looking at it is as a public file drop folder for distributing and gathering information with a single link, yet which prevents recipients from altering the existing content.
With version 10.2, ownCloud Server officially supports storage encryption with master keys stored in hardware security modules (HSM). In contrast to regular master key-based storage encryption, which stores the keys on the storage, storage encryption with keys in an HSM allows administrators to completely prevent anyone with access to the storage from accessing the data stored in ownCloud.
As a result, the bundled
encryption app has been updated to support HSM, and a standalone service (
hsmdaemon) that connects ownCloud Server and the HSM device is now available within ownCloud Enterprise Edition.
To get started with storage encryption and HSM, please get in touch with us.
For more information around the different encryption types ownCloud offers, consider this whitepaper.
When using federation to share data across ownCloud instances, deeply nested folders (e.g., folders with many sub-items) are not discovered automatically for performance reasons. This leads to several issues such as the ownCloud Desktop Client not being able to synchronize newly added or changed content unless the user navigates down the hierarchy using the web interface, which manually triggers content discovery.
Also, the size of such folders can’t be calculated, showing "Pending" instead, until the discovery is manually triggered.
To help alleviate this problem, a new
occ command has been introduced.
It can be executed regularly as a background job to discover federated shares (
This is aimed at handling this issue while providing the means for administrators to control resource usage.
When using federation, it is recommended to execute
occ incoming-shares:poll regularly using Cron jobs.
The time interval to choose between executions is a trade-off between the availability of changes in federated shares and resource consumption, which naturally depends a lot on the number of federated shares and the frequency of changes within those shares.
Executing the command once per 12 hours should be safe enough for any instance. However, the interval could be reduced to once per 2 hours for instances with a low number of federated shares.
Depending on the desired resource consumption this value should be lowered or increased based on individual expectations. To find a value that fits a specific setup, it is recommended to execute the command once, measure the execution time and set the interval so that the background job can finish before the next execution is triggered.
ownCloud Server 10.0.9 introduced the Pending Shares feature which allows users to decide whether or not they want to accept local user shares instead of just making the decision for them, giving more control thereby. In contrast, Federated shares always had to be accepted as they can originate from external, potentially untrusted, sources.
ownCloud Server 10.2 introduces a global option to automatically accept federated shares originating from trusted servers. This option enables providers of several instances (e.g., an external and an internal instance) to facilitate or automate data exchange between them, not requiring users to accept shares.
|For security reasons, federated shares from untrusted servers will never be accepted automatically.|
In the spirit of self-service, ownCloud Server 10.2 introduces new options for users that previously were reserved for global admin settings:
As discussed in the section above, there are global options for Pending Shares regarding federated as well as regular user/group shares. To give users more control over the sharing behavior in the scope of their account, user-based override options were introduced that allow users to enable/disable Pending Shares for themselves if the instance’s global setting is disabled (when "Automatically accept new incoming local user shares" is enabled). The two new checkboxes can be found in the 'Sharing' settings panel of personal settings.
In addition to the option "Allow username autocompletion in share dialog" in the global 'Sharing' settings, users can now autonomously decide to opt-out of autocompletion to protect their privacy. When enabled, other users need to enter a user’s full identifier to be able to share with them. This option is not a general override but an opt-out, meaning it can only be used when "Allow username autocompletion in share dialog" is enabled. The new checkbox is available in the 'Sharing' settings panel of personal settings.
Added email footer with motto in email for changing passwords. If you use customized email templates, it is necessary to adapt those to incorporate the footer. Please compare the original templates with your custom templates (
Repair steps can now be executed individually in case one would need to be run again. Repair steps are employed to clean up and resolve issues from former versions. Usually, they run during upgrades, but some scenarios make it necessary to rerun them. To save time when only specific steps need to be taken, administrators can now individually execute them using
occ maintenance:repair --listand
occ maintenance:repair --single "<repair step>".
Command for the first run wizard to reset for all users. In some cases, administrators customize the First Run Wizard in order to distribute information to users. Using
occ firstrunwizard:reset-allyou can reset the popup so that it will appear for each user upon their next login.
Added checkboxes to hide quota and password in user management. The columns in user management have been made more flexible. Using the bottom left cog wheel you can now show/hide the columns for Quota and Password.
By default, the "apps-external" directory is included in config.php during installation. For new installations, there will be two apps directories so that the bundled apps are distinguishable from the apps that were installed or updated by the administrator. Existing installations will not change but, generally, this separation is recommended in all scenarios, as it makes upgrading easier and less error-prone.
occ files:scancommand is used to scan resources on the storage and make them available in ownCloud. While previously it could only be used for all or single users and groups of users, you can now also execute it for groups where the group name contains a comma.
Allow administrators to enable/disable medial search for users and groups. Medial search is used to get search results when typing keys within a search term in autocomplete fields (e.g. when typing "ter" you’ll find "Peter"). Depending on the configuration of available search terms (e.g., attributes from LDAP), search results can deliver better results without medial search. For these reasons medial search can now be enabled/disabled for user (
'accounts.enable_medial_search') and group (
'groups.enable_medial_search') search. See config.sample.php for more information.
Added a new occ command,
background:queue:execute, for running cron jobs manually.
Added two new
statuslists the current background job queue status
deleteremoves a single background job, identified by its id.
Fixed public link share default expiration behavior #34971. Previously, when a default expiration date for public links had been set by an administrator (without enforcement option), the default value has been applied upon link creation even when a user removed it. The only way to create a link without expiration date was to subsequently edit it and remove the expiration date. This has been fixed to work as expected.
Better support for international email addresses after Swiftmailer update #34759
Improved speed of apps list settings page by caching integrity check results #34584
Improved upgrade speed when migrating avatars from oC < 10 #34592
Improved performance and memory usage of account sync service #34546
Store quota overrides in the
oc_preferencestable #34467. In former versions, functionality has been introduced to preserve quota values either imported via LDAP attributes against manual changes by the administrator in ownCloud user management, or via the provisioning API. This functionality works again properly. If you sync accounts from LDAP and have a quota attribute specified in LDAP, each
user:syncrun will set the quota values to the ones from LDAP, no matter if they were changed manually.
Images are again properly rotated now based on EXIF rotation, also affects gallery app #34356
An exception is logged when a background job class is not found - 34723
|This section will be updated if further issues become known.|
Server 10.2 accidentally changes the location of user avatars on the storage from
data/.., making existing avatars unavailable and storing uploaded avatar images in the wrong location. The next release will correct the behavior.
The HTML email that confirms a successful password change is rendered in plain text. Please apply this patch to fix the issue.
WebDAV Locks: When a file in a folder is locked, exclusively locking the parent folder currently still works ("conflicting lock"; divergent from RFC 4918))

Added CORS headers for many existing API calls, required for Phoenix #34476
Remove classes that were deprecated since OC 8.0.0: OCP\Config, OCP\PERMISSION_XXX, OCP\Template #34927
A capability has been added to the Capabilities API to allow clients to check whether the server supports the details parameter for private links, e.g., as a direct link to a resource’s sharing or versions tab in the web interface #35104
ownCloud Server 10.1.1 is a hotfix follow-up release that takes care of an issue with loading updated apps. Instead of updating the app versions to their new values in the database, the old version value is written causing the process to repeat with every request.
This issue can cause high load on the database, especially in large installations. If you have already upgraded to 10.1.0, we strongly recommend upgrading to 10.1.1. You can expect minimal downtime for the upgrade to this patch release.
Apart from this patch release, please consider the ownCloud Server 10.1.0 release notes.
Dear ownCloud administrator, please find below the changes and known issues in ownCloud Server 10.1 that need your attention. You can also read the full ownCloud Server changelog for further details on what has changed.
Starting with this release, ownCloud Server and the app ecosystem will follow the principles of Semantic Versioning. This step was taken to benefit operators by clearly indicating the contents and upgrade procedures of new releases via version numbers. Practically, the versioning scheme will follow the "Major.Minor.Patch" (or "Breaking.Feature.Fix") format. App developers need to re-release their apps to make them compatible with the new version. For details, please refer to this blog post.
occ upgrade pulls app updates from the ownCloud Marketplace to make sure that not only the Server itself but also the installed apps are kept up-to-date. In line with the new versioning principles
occ upgrade as well as the Market App now make a difference between major and minor app updates. Practically, this means that during a minor Server upgrade only new minor app versions will be installed. This is to make sure that apps with breaking changes will not be automatically installed when upgrading the Server. The
--major option for
occ upgrade and
occ market:install provides the means for administrators to force installing new major app versions. Additionally, the Market App now includes a version picker to enable administrators to choose which version of an app they want to install or upgrade to.
Version 10.1 delivers all the prerequisites to be compatible with the Microsoft Office Online Server Integration (WOPI) that is about to become available. This enables providers to integrate ownCloud Server with Microsoft’s Office Online Server which brings users the benefits of working on Office documents in the browser as well as collaboratively with other users. The integration will work with MS Office Online Server (on-premise) out-of-the-box. We kindly ask you to get in touch with us if you want to make use of the Office 365 (cloud) version of Office Online.
ownCloud Server 10.1 introduces WebDAV Locks that allow clients to lock and unlock resources to prevent other users from making changes. The feature has been implemented as a prerequisite for manual file locking and MS Office Online Server compatibility. In the current state, file locking is only available via API. Users can recognize locked files via the "lock" icon in the file list. Additionally a lock owner (the user who locked the file) can manually unlock them via the "Locks" tab in the right sidebar. The "Locks" tab will only appear for files that have active locks.
Federation enables instances of ownCloud and other supporting platforms to exchange information. It allows users to share data across installations building a worldwide collaboration network of decentralized nodes - each under the full control of it’s provider. Together with the other vendors the underlying OpenCloudMesh API specification has been shifted to a new level to clean up the interface, improve its stability and to set the foundation for future feature improvements. ownCloud Server 10.1 is compliant with the new specification proposal. The introduction of the new specification does not involve changes in functionality for users.
Version 10.1 comes with a new scope for Collaborative Tags called "Static Tags". In addition to the other tag scopes, these tags are intended to be supplied by administrators and linked with policies in the File Firewall, Document Classification or Workflows, for example. Every user will be able to see these tags assigned to files but only users in specified groups have the permission to assign or unassign them. This makes it possible to equip certain users with the means to impose pre-defined policies upon files. To create such tags administrators need to use the Collaborative Tags Management extension.
The user/group deletion in the users page now has a confirmation dialog to prevent unintentional user deletion
The default public link share name has been changed to be "Public link" instead of formerly the file or folder’s name

Dear ownCloud administrator, please find below the changes and known issues in ownCloud Server 10.0.10 that need your attention. You can also read the full ownCloud Server changelog for further details on what has changed.
After announcing the future deprecation of PHP 5.6 and 7.0 with the 10.0.8 release, ownCloud Server now follows up by officially adding PHP 7.2 support. The Server Core and all apps maintained by ownCloud have received a full QA cycle and are proven to work reliably with PHP 7.2. ownCloud Server is also being prepared for PHP 7.3, which is scheduled to become available by the end of 2018.
If you are still using versions 5.6 or 7.0, please plan an upgrade to 7.2 soon. See the system requirements in the ownCloud Documentation.
With PHP 7.2 some extensions have changed. If you have not yet upgraded, you need to install
In previous versions, administrators created local users by entering a username and a password. In many cases this is undesirable, as administrators set the password for new users and need to provide it via a second communication channel. For this reason the local user creation flow has been changed to expect a username and an email address, which will be used to send an activation link to new users.
This way user creation is easier and more secure as new users are informed automatically and can choose a password in self-service. For cases where administrators want to set the initial password, it’s possible to deviate from the default by setting the option "Set a password for new users" on the bottom left settings cog. The former option "Send email to new users" has been removed, as this change made it obsolete.
ownCloud Server 10.0.10 introduces an HTTP API for search functionality. It enables the use of search terms to query the server and the delivery of search results via HTTP (WebDAV). In upcoming releases, ownCloud clients will make use of it to search content on the server, without the need to have them available locally.
In combination with the Full-Text Search integration, which is soon to be released as an ownCloud Server extension (Community Edition), HTTP API for Search will boost usability and productivity for users. For example, they will be able to search through all the content which they store in their account and quickly find files on their smartphones.
Together with the new server version, another security-enhancing extension is available, Brute Force Protection. This extension is tasked with preventing attackers from guessing user passwords (brute-force attack) by delaying subsequent failed login attempts for a user account from the same IP address.
While in the past similar functionality was only achievable via third party applications, such as Fail2Ban, this extension provides the functionality natively, configurable by ownCloud administrators on the Security settings section.
The new extension supersedes the former Security extension together with the new Password Policy extension, which has been released with ownCloud Server 10.0.9. This community-contributed extension is well-tested, but out of ownCloud’s general support scope. However, individual support can be obtained on request.
The reliability of the file upload feature in the ownCloud web interface has been improved. When uploading larger amounts of data on unreliable connections (e.g., on the train or with mobile data) you have to deal with interruptions and timeouts, which in the past required users to restart stalled uploads from the beginning in the worst case.
On top of ownCloud’s chunking mechanism, which splits large files into pieces and uploads them separately, there’s new logic that takes care of retrying stalled chunks. With this, uploads can now continue from the point they froze when a connection becomes available again.
System groups in ownCloud can have many purposes. They can be used for sharing with many users at once, for feature and access restrictions, or for storage mounts to specific users - just to name a few. In some cases, especially in larger deployments, it’s undesirable that groups which are used for other purposes are also available for sharing. To prevent users from sharing with such groups, administrators can now blacklist the respective system groups using the option "Exclude groups from receiving shares" in the administration settings "Sharing" section.
The occ command
user:resetpassword allows system administrators to reset or change user passwords.
It has been extended to provide the additional options
--output-link, which can be used to send a password reset link to the user via mail and output the password reset link to the command line, respectively.
This change is in line with the new local user creation flow, which is explained above, and can also be used for further processing with scripts.
See the ownCloud Documentation and the
--help option for more information.
To ensure clean and reliable operation of the ownCloud platform it is important to stay up-to-date with the latest releases for the server as well as the clients.
To take care of compatibility between the server and desktop clients, the minimum version the server will accept connections from has been raised to version
While it’s recommended to keep up with later versions, this is the new default value.
It can be changed by altering the config.php parameter
'minimum.supported.desktop.version' ⇒ '2.3.3', if absolutely necessary.
Usually ownCloud renders mail notifications in the language of the recipients, when they are known. For the recently improved feature to send public links with a personal note directly from the user interface, the recipients' language can’t be determined automatically, it just knows the recipients' mail addresses.
ownCloud therefore uses the language of the user who sent the notification, which can have the drawback that recipients can’t understand them. This is still the default behavior but administrators can now change it via a dropdown menu "Language used for public mail notifications for shared files" in the settings "Sharing" section.
Mail templates for share notifications do not strip line breaks from the personal note anymore.
This affects the HTML (
core/templates/mail.php) and plain text (
core/templates/altmail.php) mail templates.
The default templates shipped with ownCloud Server 10.0.10 have been modified to accommodate these changes.
If your custom theme overrides these templates, you have to follow up with the changes:
Replace the following line of the HTML template
p($l→t("Personal note from the sender: %s.", [$['personal_note']]));with
print_unescaped($l→t("Personal note from the sender: <br> %s.", $['personal_note']));.
Replace the following line of the plain text template
print_unescaped($l→t("Personal note from the sender: %s.", [$['personal_note']]));with
print_unescaped($l→t("Personal note from the sender: \n %s.", $['personal_note']));.
Allow automated SSL certificate verifications for CAs other than Let’s Encrypt. See #31858 for further details.
"/" and "%" are now valid characters in group names. See #31109 for further details.
New audit events for login action with token or Apache. See #31985 for further details.
Log entries for exceeding user quota: Loglevel changed to "debug" (Insufficient storage exception is now logged with "debug" log level).
The app for embedding external sites to the app launcher ("external") now supports icons that originate from theme apps.
The occ command to deactivate storage encryption (
occ encryption:decrypt-all) has received stability improvements and can now read the required recovery key from an environment variable which is very helpful for a scripted per-user decryption process.
ownCloud Server 10.0.10 takes care of 10.0.9 known issues and provides remedies for several others:
The Password Policy extension now works with two- or multi-factor authentication extensions. See #32058 for further details.
Versionsfeature now works also when the
Commentsapp is disabled. See #32208 for further details.
E-mail addresses with subdomains with hyphens are now also accepted for public link emails. See #32281 for further details.
Allow null in "Origin" header for third party clients that send it with WebDAV. See #32189 for further details.
Properly log failed message when token based authentication is enforced (Fail2Ban). See #31948 for further details.
Deleting a user now also properly deletes their external storages and storage assignations. See #32069 for further details.
Lockout issues with wrong passwords for Windows Network Drives are mitigated: Fixed mount config in front-end to only load once to avoid side effects. See #32095 for further details.
Fixed update issue related to oc_jobs when automatically enabling market app to assist for update in OC 10. See #32573 for further details.
Fixed missing migrations in files_sharing app and add indices to improve performance. See #32562 for further details.
Fixed issue with spam filters when sending public link emails. See #32542 for further details.
Currently there are no known issues with ownCloud Server 10.0.10. This section will be updated in the case that issues become known.
Add information whether user can share to capabilities API. See #31824 for further details.
loadAdditionalScriptsnow also available for public link page. See #31944 for further details.
Added URL parameter to files app which opens a specific sidebar tab. See #32202 for further details.
Allow slashes in generated resource routes in app framework. See #31939 for further details.
The app for embedding external sites to the app launcher ("external") has been moved to a separate repository. It is still bundled with ownCloud Server releases and can be used normally.
Dear ownCloud administrator, please find below the changes and known issues in ownCloud Server 10.0.9 that need your attention. You can also read the full ownCloud Server changelog for further details on what has changed.
ownCloud Server 10.0.9 introduces new features to close usability gaps and to give users more control over incoming shares. Previously, shared contents would appear, unannounced, in the receiving user’s file hierarchy, and clients would start synchronizing.
Incoming shares can now have a pending state, offering the ability to accept or decline (as known from federated sharing). We anticipate that this will provide a better user experience.
In addition, the recently introduced notifications framework is being used to inform users via mail.
The bell icon in the web interface and the ownCloud Desktop Client can additionally be used to take action.
To switch to the new behavior administrators need to disable the configuration option
Automatically accept new incoming local user shares in the Sharing settings section.
By default the option will be enabled to preserve the known behavior.
Mail notifications do not, currently, support asynchronous batch processing. For this reason, ownCloud will send notification emails directly when initiating shares between users. Due to this limitation, sharing with large groups (> 50 users) can take some time and might cause load peaks. When operating installations with large groups, it is, therefore, not yet recommended to enable the feature.
In addition to the "Pending Shares" feature, ownCloud Server now provides the means to view "accepted", "pending" and "rejected" incoming shares. Leveraging the "Shared with you" filter in the left sidebar of the files view users can now list all incoming shares, their respective states and have the ability to switch between the states easily.
This improvement not only empowers users to accept rejected shares subsequently but also to restore shares that have been unshared before without requiring the owner to share it again.
To prepare ownCloud Server for new capabilities in the authentication process, we have introduced an authentication middleware, and a new major version of the Password Policy extension is now available.
Offers a defined way of inserting mandatory functionality between user authentication and user account access. For example, forcing users to accept legal agreements.
Affords the ability to interact with the user during the login process, such as retrieving user details like their email address.
The authentication middleware is currently focused on offering new features for the Password Policy extension.
The Password Policy Extension has got a new major release and has been relicensed (OCL ⇒ GPLv2) to be available for community and standard subscription users as well. It now supports password expiration and history policies for user accounts.
These features don’t apply to users imported from LDAP or other backends but only for local users created by administrators or the Guests extension.
Imposing password expiration and history policies enhances security for a number of reasons. For example, by forcing users to choose a new password, they can be prevented from using one or more of their previous passwords. In doing this, it encourages them to not use a previous password, which may be known to attackers.
Two further examples are manually expiring passwords and configuring the number of days that have to pass since the last change before the password expires. These help ensure that users change their passwords on a semi-regular basis, making them harder to crack.
However, we encourage administrators to always consider the implication of their password policies, so that they strike an appropriate balance between security and usability. For example, a high frequency of password changes, for instance, might increase security but could also decrease user satisfaction.
To help ensure a good user experience it is possible to configure:
Internal notifications (they appear on the web interface and clients).
The password history count.
The days before reminder notification are sent.
Users will always be informed when passwords have expired.
Although the above two password practices are discouraged by NIST, ownCloud is now fully compliant with common password guidelines in enterprise scenarios.
When users employ tokens for client authentication, which can be configured on the user settings page ("App passwords"), those are not affected from password policies.
When imposing password expiration policies on an existing installation it is necessary to take some further actions. Please consult `the ownCloud documentation`_ for guidance.
ownCloud Server 10.0.9 comes with the prerequisites to be ready for the new S3 Objectstore implementation "files_primary_s3", which will massively improve performance, reliability and protocol-related capabilities. The new extension is available as a technology preview via the ownCloud Marketplace and will supersede the current Objectstore extension.
It has received extensive testing and is in very good shape. However, there is no out-of-the-box migration from the current Objectstore to files_primary_s3 as this will require individual guidance.
Due to changes to the Versioning API, the ownCloud Ransomware Protection is not yet compatible with files_primary_s3. For now the Objectstore extension will continue to work as usual. Once the new implementation leaves the technology preview state and migrations have been taken care of, the current implementation will be deprecated.
As the markets are moving in the direction of the S3 protocol to communicate with object storages, ownCloud will follow this path with a clear focus. To do this, it will be a necessity to deprecate object storage via the OpenStack SWIFT protocol.
The extension will still be available as part of ownCloud Server, but it will neither be maintained nor developed any further by ownCloud, and support will be discontinued. Please make sure to move to the S3 protocol to use object storage as primary storage with future ownCloud Server versions.
In the "General" Administration settings section
Via the following OCC commands:
sudo -u www-data php occ config:app:set core legal.imprint_url <link>
sudo -u www-data php occ config:app:set core legal.privacy_policy_url <link>
These links can be displayed on all pages of the ownCloud web interface and in the footer of mail notifications. When using one of the default themes provided by ownCloud, as well as the default mail templates, configured links will be automatically included.
For customized themes or mail templates, actions are required to include the links. These are:
Add the following at the end of each HTML template to add the footer:
<?php print_unescaped($this→inc('html.mail.footer', ['app' ⇒ 'core'])); ?>
Add the following at the end of each plain text template to add the footer:
<?php print_unescaped($this→inc('plain.mail.footer', ['app' ⇒ 'core'])); ?>
The option "Exclude groups from sharing", in the administration settings "Sharing" section, enables administrators to exclude groups of users from the ability to initiate file shares. In previous versions this restriction only applied to users who were members of exactly these groups (membership of one or more non-excluded groups bypassed the restriction).
This behavior has been changed to be both more restrictive and to better cover the expectations of administrators. With ownCloud Server 10.0.9, it will apply to all users who are members of at least one of the excluded groups.
In ownCloud Server 10.0.8, the value for minimum characters to trigger the sharing autocomplete mechanism <min-chars-for-sharing-autocomplete-label> has been made configurable and set to 4 by default. As this security-enhancing change came at the expense of usability, and might only be required in special scenarios, the default value has been reverted to 2.
For increased security requirements, the
'user.search_min_length' ⇒ 2 can be adjusted. To further improve
usability, a hint has been added to inform users about the required
character count, to get suggestions.
To improve the usability of the
occ user:list command, the output has
been made configurable by using the
-a option, for including certain
attributes. This change has mainly been introduced to facilitate
automation tasks. Check the
--help option for more information.
New events are available for audit logging, among others. These include:
Changes in user specific settings
Sending public links via mail; and
Accepting and rejecting shares
When logs are forwarded to external analyzers, like Splunk,
administrators can check to add the new events. The latest version of
the Auditing extension (
admin_audit) is required.
HTML templates for
lost passwordmails have been added. This is important in case a custom theme is used and it needs manual adjustments.
The mail notifications framework, introduced with ownCloud Server 10.0.8 <new-mail-notifications-feature-label>, has been extended to provide a basic framework and notification structure, which can be used by ownCloud features and third party extensions. To support this, mail template wording and structure have been updated. Please review the templates in
apps/notifications/templates/mail/to align them with your needs.
Mail templates can now include a footer for HTML (
core/templates/html.mail.footer.php) and plain text mails (
core/templates/plain.mail.footer.php). The default templates shipped with ownCloud Server 10.0.9 contain the respective references. For customized mail templates, it is necessary to manually add the references. To do so:
Add the following at the end of each HTML template: :
<?php print_unescaped($this->inc('html.mail.footer', ['app' => 'core'])); ?>
Add the following at the end of each plain text template: :
<?php print_unescaped($this->inc('plain.mail.footer', ['app' => 'core'])); ?>
The ownCloud example theme (
theme-example), which can be used as a solid base to create custom themes, is no longer bundled with ownCloud Server. It now lives in it’s own repository on GitHub.
ownCloud Server 10.0.9 takes care of 10.0.8 known issues, and provides remedy for several others:
Issues with multiple theme apps and the Mail Template Editor #31478
OCC command to transfer data between users (
occ transfer:ownership) works as expected again. Previously, public link shares were not transferred. See #31176 for further details.
OCC commands to encrypt (
occ encryption:encrypt-all) and decrypt (
occ encryption:decrypt-all) user data work correctly again. Previously, shares might have been lost during the encryption process. See #31600 and #31590 for further details.
Files larger than 10 MB can now properly be uploaded by guest users. See #31596 for further details.
Issues with public link dialog when collaborative tags app is disabled has been resolved. See #31581 for further details.
Enabling/disabling of users by group administrators in the web UI works again. See #31489 for further details.
Issues with file upload using Microsoft EDGE are now circumvented (hard memory limit of 5 GB causing uploads to fail randomly as garbage collection for file chunks did not work properly). See #31884 for further details.
Does not work together with Multi-Factor Authentication (e.g.
twofactor_privacyidea). Please do not deploy expiration policies yet when having Two- or Multi-Factor Authentication extensions in place. This issue will be solved with the next ownCloud Server release. See #32059 for more information.
The new Password Policy feature "Password Expiration" includes an occ command to manually force password expiration. Please run it directly after imposing expiration policies on an instance with existing users. Currently the command will only work when the policy X days until user password expires has been enabled. This might be confusing and will be solved with the next release of the extension. See #66 for more information.
The symfony event for logging has been extended to include the original exception when applicable: #31623
Added Symfony event for whenever user settings are changed #31266
Added Symfony event for whenever a public link share is sent by email #31632
Added Symfony event for whenever local shares are accepted or rejected #31702
Dear ownCloud administrator, please find below the changes and known issues in ownCloud Server 10.0.8 that need your attention. You can also read the full ownCloud Server changelog for further details on what has changed.
PHP 5.6/7.0 active support has ended on January 19th 2017 / December 3rd 2017 and security support will be dropped by the end of 2018. Many libraries used by ownCloud (including the QA-Suite PHPUnit) will therefore not be maintained actively anymore which forces ownCloud to drop support in one of the next minor server versions as well. Please make sure to upgrade to PHP 7.1 as soon as possible. See the system requirements in the ownCloud documentation.
One of the usability enhancements of ownCloud Server 10.0.8 is the possibility for users to add a personal note when sending public links via mail. When using customized mail templates it is necessary to either adapt the shipped original template to the customizations or to add the code block for the personal note to customized templates in order to display the personal note in the mail notifications.
ownCloud Server 10.0.8 introduces a new extensible notification framework. Apart from technical changes under the hood the Notifications app can now also send mails for all notifications that previously were only displayed within the web interfaces (notification bell) or on the Desktop client (notifications API) like incoming federated share or Custom Group notifications, for example. In the "General" settings section users can configure whether they want to receive mails for all notifications, only for those that require an action or decide not to get notifications via mail (by default users will only receive notifications when an action is required).
When disabling or deleting user accounts in LDAP, the administrator can choose to either delete or disable respective accounts in ownCloud when executing
-m, --missing-account-action=MISSING-ACCOUNT-ACTION). User accounts that are disabled in ownCloud can now be re-enabled automatically when running
occ user:syncif they are enabled in LDAP. When this behavior is desired administrators just need to add the
-r, --re-enableoption to their cron jobs or when manually executing
Furthermore it is now possible to execute
occ user:synconly for single (
-u, --uid=UID) or seen (
-s, --seenOnly) users (users that are present in the database and have logged in at least once). These new options provide more granularity for administrators in terms of managing
Another notable change in behavior of
occ user:syncis that administrators now have to explicitly specify the option
-c, --showCountto display the number of users to be synchronized.
New events have been added to be used for audit logging, among others. These include configuration changes by administrators and users, file comments (add/edit/delete) and updating existing public links. When logs are forwarded to external analyzers like Splunk, administrators can check to add the new events. The latest version of the Auditing extension (admin_audit) is required.
With ownCloud 10 file integrity checking by computing and matching
checksums has been introduced to ensure that transferred files arrive at
their target in the exact state as their origin. In some rare cases
wrong checksums can be written to the database leading to
synchronization issues with e.g. the Desktop Client. To mitigate such
situations a new command
occ files:checksums:verify has been
introduced. The command recalculates checksums either for all files of a
user or for files within a specified path, and compares them with the
values in the database. Naturally the command also offers an option to
repair incorrect checksum values (
-r, --repair). Please check the
available options by executing
occ files:checksums:verify --help.
Note: Executing this command might take some time depending on the file
For security reasons the default value for minimum characters to trigger
the sharing autocomplete mechanism has been set to "4" (previously it
was set to "2"). This is to prevent people from easily downloading
lots of email addresses or user names by requesting their first letters
through the API. As it is a trade-off between security and usability for
some scenarios this high security level might not be desirable.
Therefore the value now is configurable via the config.php option
'user.search_min_length' ⇒ 4,. Please check which value fits your
With ownCloud 10 the
File Drop feature has been merged with public
link permissions. This kind of public link does not give recipients
access to any content, but it gives them the possibility to
files. As a result, it might not always be desirable to enforce
password protection for such shares. Given that, passwords for public
links can now be enforced based on permissions (read-only, read &
write, upload only/File Drop). Please check the administration settings
`Sharing` section and configure as desired.
By verifying signature files the integrity check ensures that the code
running in an ownCloud instance has not been altered by third parties.
Naturally this check can only be successful for code that has been
obtained from official ownCloud sources. When providing custom apps
(like theme apps) that do not have a signature, the integrity check will
fail and notify the administrator. These apps can now be excluded from
the integrity check by using the config.php option
'integrity.ignore.missing.app.signature' ⇒ ['app_id1', 'app_id2', 'app_id3'],.
See config.sample.php for more information.
It is now possible to modify user details like display names or mail
addresses via the command
occ user:modify. Please append
Apart from using the
occ files:scan command for single users and
whole instances it can now be executed for groups using
-g, --groups=GROUPS. Please append
--help for more information.
When using syslog as the log type (
'log_type' ⇒ 'syslog', in
config.php) the default format has been changed to include request
IDs for easier debugging. Additionally the log format has been made
'log.syslog.format' in config.php. If you require
a certain log format, please check the new format and
config.sample.php on how to change it.
For security reasons federated sharing (sharing between different
ownCloud instances) strictly requires HTTPS (SSL/TLS). When this
behavior is undesired the insecure fallback to HTTP needs to be enabled
explicitly by setting
'sharing.federation.allowHttpFallback' ⇒ false,
true in config.php.
Upgrading to 10.0.8 includes migrations related to auth_tokens (app passwords). When users have created app passwords as separate passwords for their clients the upgrade duration will increase depending on user count. Please consider this when planning the upgrade.
When the "Sharing" settings option
Allow users to send mail notifications for shared files for public
links is enabled, users can send public links via mail from within the
web interface. The behavior of the autocomplete when entering mail
addresses in the public link share dialog has been changed. Previously
the autocomplete queried for local users, users from federated address
books and contacts from CardDAV/Contacts App. As public links are not
intended for sharing between ownCloud users (local/federated), those
have been removed. Contacts synchronized via CardDAV or created in the
Contacts app will still appear as suggestions.
occ notifications:generate can be used to send notifications to individual users or groups.
With 10.0.8 it is also capable of including links to such notifications using the
-l, --link=LINK option.
--help for more information.
There is also
to conduct such tasks from the web interface but it is currently limited to send notifications to all users.
For now administrators can use the `occ command if more granularity is required.
For security reasons ownCloud has a Same-Origin-Policy that prevents
requests to ownCloud resources from other domains than the domain the
backend server is hosted on. If ownCloud resources should be accessible
from other domains, e.g. for a separate web frontend operated on a
different domain, administrators can now globally specify policy
exceptions via CORS (Cross-Origin Resource Sharing) using
'cors.allowed-domains' in config.php. Please check
config.sample.php for more information.
The Mail Template Editor has been unbundled from the default apps and is not shipped with the Server anymore. When upgrading ownCloud will try to automatically install the latest version from the ownCloud Marketplace in case the app was installed before.
If this is not possible (e.g. no internet connection or clustered setup) you will either need to disable the app
occ app:disable templateeditor) or
download and install it manually.
Login failedlog entries have been removed (see 10.0.7 known issues)
The Provisioning API can now properly set default or zero quota
User quota settings can be queried through Provisioning API
A regression preventing a user from setting their e-mail address in the settings page has been fixed
File deletion as a guest user works correctly (trash bin permissions are checked correctly)
Issues with multiple theme apps and Mail Template Editor
As of ownCloud Server 10.0.5 it is only possible to have one theme app enabled simultaneously. When a theme app is enabled and the administrator attempts to enable a second one this will result in an error. However, when also having the Mail Template Editor enabled in this scenario the administrators "General" settings section will be displayed incorrectly. As a remedy administrators can either uninstall the second theme app or disable the Mail Template Editor app.
occ transfer:ownershipdoes not transfer public link shares if they were created by the target user (reshare).
The global JS variable
oc_current_userwas removed. Please use the public method
Lots of new Symfony events have been added for various user actions, see changelog for details, or the documentation ticket.
When requesting a private link there is a new HTTP response header
Webdav-Locationthat contains the WebDAV path to the requested file while the
Locationstill points at the frontend URL for viewing the file.
ownCloud Server 10.0.7 is a hotfix follow-up release that takes care of an issue regarding OAuth authentication.
Please consider the ownCloud Server 10.0.5 release notes.
ownCloud Server 10.0.6 is a hotfix follow-up release that takes care of an issue during the build process (https://github.com/owncloud/core/pull/30265). Please consider the ownCloud Server 10.0.5 release notes.
Dear ownCloud administrator, please find below the changes and known issues in ownCloud Server 10.0.5 that need your attention. You can also read the full ownCloud Server changelog for further details on what has changed.
ownCloud catches up with new web technologies. This has mainly been introduced for the open-source community to test and give feedback. PHP 7.2 is not yet supported nor recommended for production scenarios. ownCloud is going to fully support PHP 7.2 with the next major release.
Please make sure to have the PHP extension installed before upgrading.
The theming behavior has been changed so that only a single theme can be active concurrently. This change ensures that themes can not interfere in any way (e.g., override default theming in an arbitrary order). Please make sure to have the desired theme enabled after upgrading.
Please switch to the new External Storage: Dropbox app with Dropbox API v2 support to continue providing Dropbox external storages to your users.
ownCloud Server 10.0.4 known issue is resolved.
Known issues are resolved: Mail Template Editor works again, got support for app themes and additional templates were added for customization.
Mail Template Editor is still bundled with ownCloud Server but will soon be released as a separate app to ownCloud Marketplace.
When using application passwords, log entries related to
Login Failedwill appear, please upgrade to 10.0.7 and check the fix mentionned in its release notes.
Dear ownCloud administrator, please find below the changes and known issues in ownCloud Server 10.0.4 that need your attention. You can also read the full ownCloud Server 10.0.4 changelog for further details on what has changed.
The "Restrict users to only share with users in their groups" option, in the Sharing settings, restricts users to only share with groups which they are a member of, while simultaneously prohibiting sharing with single users that do not belong to any of the users’ groups.
To make this more granular, we split this option into two parts and added "Restrict users to only share with groups they are member of", which differentiates between users and groups. Doing so makes it possible to restrict users from sharing with all users of an installation, limiting them to only being able to share with groups which they are a member of, and vice versa.
The ownCloud sharing dialog displays users according to their display name. As users can choose their display name in self-service (which can be disabled in config.php) and display names are not unique, it is possible that a user can’t distinguish sharing results.
To cover this case the displayed user identifiers are now configurable. In the Sharing settings administrators can now configure the display of either mail addresses or user ids.
We recommend to use this command when directed to do so in the upgrade process. Please refer to the occ command’s files:scan –repair documentation for more information.
Administrators can use the output of this command when using a network firewall, to check the appropriateness of configured rules or to get assistance when setting up.
As ownCloud needs to behave differently when operating in a clustered setup versus a single instance setup, the new
operation.mode has been added.
It can take one of two values:
'operation.mode' ⇒ 'clustered-instance',.
Currently the Market App (ownCloud Marketplace integration) does not support clustered setups and can do harm when used for installing or updating apps. The new config setting prevents this and other actions that are undesired in cluster mode.
When operating in a clustered setup, it is mandatory to set this option. Please check the config_sample_php_parameters documentation for more information.
When file uploads are interrupted for any reason, already uploaded file parts (chunks) remain in the underlying storage so that the file upload can resume in a future upload attempt. However, resuming an upload is only possible until the partial upload is expired and deleted, respectively.
To clean up chunks (expire and delete) originating from unfinished uploads, administrators can use this newly introduced command. The default expiry time is two days, but it can be specified as a parameter to the command.
It is recommended to configure CRON to execute this background job regularly.
It is not included in the regular ownCloud background jobs so that the administrators have more flexibility in scheduling it. Please check the background jobs configuration documentation for more information.
When administrators did intentional changes to the ownCloud code they
now have the ability to exclude certain files from the integrity
checker. Please check
config.sample.php for the usage of
When upgrading to 10.0.4 migrations may increase update duration dependent on number of files.
Users with outdated browsers might get warnings. See the list of supported browser versions.
When using application passwords, log entries related to
Login Failedwill appear, please upgrade to 10.0.7 and check the fix mentioned in its release notes.
Dear ownCloud administrator, please find below the changes and known issues of ownCloud Server 10.0.3 that need your attention:
The full ownCloud Server 10.0.3 changelog can be found here: https://github.com/owncloud/core/blob/stable10/CHANGELOG.md
It is now possible to directly upgrade from 8.2.11 to 10.0.3 in a single upgrade process.
Added occ command to list routes which can help administrators setting up network firewall rules.
occ upgradeis now verbose by default. Administrators may need to adjust scripts for automated setup/upgrade procedures that rely on `occ upgrade' outputs.
Reenabled medial search by default::
Enables partial search in sharing dialog autocompletion (e.g. a user wants to share with the user "Peter": Entering "pe" will find the user, entering "ter" will only find the user if the option is enabled)
New default is set to enabled as there is no performance impact anymore due to the introduction of the user account table in ownCloud Server 10.0.1.
Please check the setting. You need to disable it explicitly if the functionality is undesired.
All database columns that use the fileid have been changed to bigint (64-bits). For large instances it is therefore highly recommended to upgrade in order to avoid reaching limits.
Upgrade and Market app information::
appstoreenabledsetting from config.php. If you want to disable the app store / Marketplace integration, please disable the Market app.
Added setting `upgrade.automatic-app-update' to config.php to disable automatic app updates with `occ upgrade' when Market app is enabled
On upgrade from OC < 10 the Market app won’t be enabled if
appstoreenabledwas false in config.php.
Clustering: Better support of read only config file and apps folder
Default minimum desktop client version in config.php is now 2.2.4.
Added quotes in boolean result values of
Setting up SFTP external storages with keypairs does not work. https://github.com/owncloud/core/issues/28669
If you have storage encryption enabled, the web UI for encryption will ask again what mode you want to operate with even if you already had a mode selected before. The administrator must select the mode they had selected before. https://github.com/owncloud/core/issues/28985
Uploading a folder in Chrome in a way that would overwrite an existing folder can randomly fail (race conditions). https://github.com/owncloud/core/issues/28844
Federated shares can not be accepted in WebUI for SAML/Shibboleth users
For MariaDB users: Currently, Doctrine has no support for the breaking changes introduced in MariaDB 10.2.7, and above. If you are on MariaDB 10.2.7 or above, and have encountered the message
1067 Invalid default value for `lastmodified, please apply this patch to Doctrine. We expect this bug to be fixed in ownCloud 10.0.4. For more information on the bug, check out the related issue.
When updating from ownCloud < 9.0 the CLI output may hang for some time (potentially up to 20 minutes for big instances) whilst sharing is updated. This can happen in a variety of places during the upgrade and is to be expected. Please be patient as the update is performed and the output will continue as normal.
Hello ownCloud administrator, please read carefully to be prepared for updates and operations of your ownCloud setup.
A new update path: ownCloud 10.0.1 contains migration logic to allow upgrading directly from 9.0 to 10.0.1.
Marketplace: Please create an account for `the new marketplace`_. Access to optional ownCloud extensions and enterprise apps will be provided by the marketplace from now on. Currently some apps are still shipped with the tarballs / packages and will be moved to the marketplace in the near future.
Apps: LDAP, gallery, activity, PDF viewer, and text editor were moved to the marketplace.
Updates with marketplace: During the upgrade, enabled apps are also updated by fetching new versions directly from the marketplace. If during an update, sources for some apps are missing, and the ownCloud instance has no access to the marketplace, the administrator needs to disable these apps or manually download and provide the apps before updating.
App updates: Third party apps are not disabled anymore when upgrading.
Upgrade migration test: The upgrade migration test,
--skip-migration-tests, has been removed.
The template editor app is not included in the 10.0.1 release due to technical reasons, but will be distributed via the marketplace. However, you can still edit template files manually.
Settings design: Admin, personal pages, and app management are now merged together into a single "Settings" entry.
Disable users: The ability to disable users in the user management panel has been added.
Password Policy: Rules now apply not only to link passwords but also to user passwords.
Client: You need to update to the latest desktop client version.
Cron jobs: The user account table has been reworked. As a result the Cron job for syncing user backends, e.g., LDAP, needs to be configured.
Logfiles: App logs, e.g., auditing and owncloud.log, can now be split, see: xref:configuration/server/config_sample_php_parameters.adoc#logging.
Converting a Database from e.g.
occ db:convert-type currently doesn’t work. See
https://github.com/owncloud/core/issues/27075 for more info.
This causes an SQL error such as the following:
sudo -u www-data php occ market:install user_ldap user_ldap: Installing new app ... user_ldap: An exception occurred while executing 'CREATE TABLE `ldap_user_mapping` (`ldap_dn` VARCHAR(255) DEFAULT '' NOT NULL, `owncloud_name` VARCHAR(255) DEFAULT '' NOT NULL, `directory_uuid` VARCHAR(255) DEFAULT '' NOT NULL, UNIQUE INDEX ldap_dn_users (`ldap_dn`), PRIMARY KEY(`owncloud_name`)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_bin ENGINE = InnoDB ROW_FORMAT = compressed': SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'ldap_user_mapping' already exists
This can be safely ignored. And the app can be used after enabling it.
Please be aware that when upgrading an existing ownCloud installation
that already has
user_ldap this error will not occur. It was fixed by
https://github.com/owncloud/core/pull/27982. However, this could happen
for other apps as well that use
database.xml. If it does please use the same workaround.
We will re-enable SSO for LDAP users with an update of the app in the market after completing internal testing.
To uninstall, disable the app with occ and rm the app directory.
All shares, comments, and tags on the moved files will be lost.
Existing LDAP users only show up in the user management page and the share dialog after being synced
The account table introduced in ownCloud 10.0.0 significantly reduces
LDAP communication overhead. Password checks are yet to be accounted
for. LDAP user metadata in the account table will be updated when users
log in or when the administrator runs
occ user:sync "OCA\User_LDAP\User_Proxy".
We recommend setting up a nightly Cron job to keep metadata of users not actively logging in up to date.
PHP 7.1 support added (supported PHP versions are 5.6 and 7.0+)
The upgrade migration test has been removed; (Option
"--skip-migration-tests"removed from update command)
Requires to use the latest desktop client version 2.3
Third party apps are not disabled anymore when upgrading
User account table has been reworked. CRON job for syncing with e.g., LDAP needs to be configured (see Syncing User Accounts for more information)
LDAP app is not released with ownCloud 10.0.0 and will be released on the marketplace after some more QA
files_drop app is not shipped anymore as it’s integrated with core now. Since migrations are not possible you will have to reconfigure your drop folders (in the `Public Link' section of the sharing dialog of the respective folders).
SAML/Shibboleth with device-specific app passwords: No migration possible; Users need to regenerate device-specific app passwords in the WebUI and enter those in their clients.
For security reasons status.php can now be configured in config.php to not return server version information anymore (`version.hide'; default `false'). As clients still depend on version information this is not yet recommended. The default will change to `true' with 10.0.2 once clients are ready.
Order of owncloud.log entries changed a bit, please review any application (e.g. fail2ban rules) relying on this file
FTP external storage moved to a separate app (https://marketplace.owncloud.com/apps/files_external_ftp)
"Local" storage type can now be disabled by sysadmin in config.php (to prevent users mounting the local file system)
Full changelog: https://github.com/owncloud/core/wiki/ownCloud-10.0-Features
Background jobs (cron) can now run in parallel
Update notifications in client via API - You can now be notified in your desktop client about available updates for core and apps. The notifications are made available via the notifications API.

PSR-4 autoloading forced for
OCP\, optional for
OCA\docs at xref:developer_manual/app/classloader.adoc
More cleanup of the sharing code (ongoing)
9.0 requires .ico files for favicons. This will change in 9.1, which will use .svg files. See Changing favicon in the Developer Manual.
Home folder rule is enforced in the user_ldap application in new ownCloud installations; see configuration/user/user_auth_ldap. This affects ownCloud 8.0.10, 8.1.5 and 8.2.0 and up.
The Calendar and Contacts apps have been rewritten and the CalDAV and
CardDAV backends of these apps were merged into ownCloud core. During
the upgrade existing Calendars and Addressbooks are automatically
migrated (except when using the
IMAP user backend). As a fallback for
failed upgrades, when using the
IMAP user backend or as an option to
test a migration
dav:migrate-addressbooks scripts are available (only in ownCloud
9.0) via the
occ command. See configuration/server/occ_command.
After upgrading to ownCloud 9.0 and before continuing to upgrade to 9.1 make sure that all of your
and your users Calendars and Addressbooks are migrated correctly. Especially when using the
Updates on systems with large datasets will take longer, due to the addition of checksums to the ownCloud database. See https://github.com/owncloud/core/issues/22747.

ownCloud plus dependencies, including Apache and PHP.
installs only ownCloud. This is useful for custom LAMP stacks, and
allows you to install your own LAMP apps and versions without packaging
conflicts with ownCloud. See installation/linux_installation.
New option for the ownCloud admin to enable or disable sharing on individual external mountpoints (see External Storage GUI Mount Options). Sharing on such mount points is disabled by default.
owncloud-enterprise packages are no longer available for CentOS 6, RHEL6, Debian 7, or any version of Fedora. A new package, owncloud-enterprise-files, is available for all supported platforms, including the above. This new package comes without dependencies, and is installable on a larger number of platforms. System administrators must install their own LAMP stacks and databases. See https://owncloud.org/blog/time-to-upgrade-to-owncloud-9-0/.
New location for Linux package repositories; ownCloud admins must manually change to the new repos. See maintenance/upgrade
PHP 5.6.11+ breaks the LDAP wizard with a `Could not connect to LDAP' error. See https://github.com/owncloud/core/issues/20020.
config.php is set to 0 by default. This
prevents unnecessary update checks and improves performance. If you are
using external storage mounts such as NFS on a remote storage server,
set this to 1 so that ownCloud will detect remote file changes.
XSendFile support has been removed, so there is no longer support for
serving static files from your ownCloud server.
LDAP issue: 8.2 uses the
memberof attribute by default. If this is not
activated on your LDAP server your user groups will not be detected, and
you will see this message in your ownCloud log:
Error PHP Array to string conversion at /var/www/html/owncloud/lib/private/template/functions.php#36.
Fix this by disabling the
memberof attribute on your ownCloud server
occ command, like this example on Ubuntu Linux:
sudo -u www-data php occ ldap:set-config "s01" useMemberOfToDetectMembership 0
sudo -u www-data php occ ldap:show-config to find the correct
sNN value; if there is not one then use empty quotes,
Users of the Linux Package need to update their repository setup as described in this blogpost.
Use APCu only if available in version 4.0.6 and higher. If you install
an older version, you will see a
APCu below version 4.0.6 is installed, for stability and performance reasons we recommend to update to a
newer APCu version warning on your ownCloud admin page.
SMB external storage now based on
php5-libsmbclient, which must be downloaded from the ownCloud software repositories
Download from link feature has been removed.
index.html files in the
data/ directory are now
updated after every update. If you make any modifications to these files
they will be lost after updates.
The SabreDAV browser at
/remote.php/webdav has been removed.
Using ownCloud without a
trusted_domain configuration will not work
The logging format for failed logins has changed and considers now the
proxy configuration in
A default set of security and privacy HTTP headers have been added to
.htaccess file, and ownCloud administrators may now
customize which headers are sent.
More strict SSL certificate checking improves security but can result in
cURL error 60: SSL certificate problem: unable to get local issuer
certificate errors with certain broken PHP versions. Please verify
your SSL setup, update your PHP or contact your vendor if you receive
The persistent file-based cache (e.g. used by LDAP integration) has been
dropped and replaced with a memory-only cache, which must be explicitly
configured. See configuration/user/user_auth_ldap. Memory cache
configuration for the ownCloud server is no longer automatic, requiring
installation of your desired cache backend and configuration in
config.php (see configuration/server/caching_configuration.)
OC_User_HTTP backend has been removed. Administrators are
encouraged to use the
user_webdavauth application instead.
ownCloud ships now with its own root certificate bundle derived from Mozilla’s root certificates file. The system root certificate bundle will not be used anymore for most requests.
When you upgrade from ownCloud 8.0, with encryption enabled, to 8.1, you must enable the new encryption backend and migrate your encryption keys.
Encryption can no longer be disabled in ownCloud 8.1. It is planned to re-add this feature to the command line client for a future release.
It is not recommended to upgrade encryption-enabled systems from ownCloud Server 8.0 to version 8.1.0 as there is a chance the migration will break. We recommend migrating to the first bugfix release, ownCloud Server 8.1.1.
Due to various technical issues, by default desktop sync clients older
than 1.7 are not allowed to connect and sync with the ownCloud server.
This is configurable via the

config.php and the
Enforce SSL option within the Admin-Backend was removed.
This now needs to be configured like described in
Hardening and Security Guidance.
WebDAV file locking was removed in ownCloud 8.1 which causes Finder on macOS to mount WebDAV read-only.
When you are configuring the LDAP user and group backend application, ownCloud may not auto-detect the LDAP server’s port number, so you will need to enter it manually.
There is no preview icon displayed for text files when the file contains fewer than six characters.
When you mount a Federated Cloud share from a remote ownCloud server, you cannot re-share it with your local ownCloud users. (See Federated Cloud Sharing Configuration to learn more about federated cloud sharing)
If you are using the Encryption application and upgrading from older versions of ownCloud to ownCloud 8.0, you must manually migrate your encryption keys.
If Multiviews are enabled in your Apache configuration, this may cause problems with content negotiation, so disable Multiviews by removing it from your Apache configuration. Look for lines like this:
<Directory /var/www/owncloud> Options Indexes FollowSymLinks Multiviews
Multiviews and restart Apache.
ownCloud’s file scanner does not follow symlinks, which could lead to infinite loops. To avoid this do not use soft or hard links in your ownCloud data directory.
Creating an ownCloud group with a comma in the group name causes ownCloud to treat the group as two groups.
On Windows servers Hebrew file names grow to five times their original size after being translated to Unicode.
Google Drive tries to download the entire file into memory, then write it to a temp file, and then stream it to the client, so very large file downloads from Google Drive may fail with a 500 internal server error.
When you activate the Encryption application on a running server that has large numbers of files, it is possible that you will experience timeouts. It is best to activate encryption at installation, before accumulating large numbers of files on your ownCloud server.
The SharePoint Drive application does not verify the SSL certificate of the SharePoint server or the ownCloud server, as it is expected that both devices are in the same trusted environment.
Federated Cloud Sharing (formerly Server-to-Server file sharing)does not work with Shibboleth .
When files are uploaded directly to a SWIFT share mounted as external storage in ownCloud, the files do not appear in ownCloud. However, files uploaded to the SWIFT mount through ownCloud are listed correctly in both locations.
The current SWIFT implementation is incompatible with any application that uses direct file I/O and circumvents the ownCloud virtual filesystem. Using the Encryption application on a SWIFT object store incurs twice as many HTTP requests and increases latency significantly.
When you are configuring the LDAP user and group backend application, ownCloud may not auto-detect the LDAP server’s port number, so you will need to enter it manually.
Prior to 7.0.4, LDAP searches were substring-based and would match search attributes if the substring occurred anywhere in the attribute value. Rather, searches are performed on beginning attributes. With 7.0.4, searches will match at the beginning of the attribute value only. This provides better performance and a better user experience.
Substring searches can still be performed by prepending the search term
*. For example, a search for
te will find Terri, but not Nate:
occ ldap:search "te"
If you want to broaden the search to include Nate, then search for
occ ldap:search "*te"
Refine searches by adjusting the
User Search Attributes field of the
Advanced tab in your LDAP configuration on the Admin page. For example,
if your search attributes are
sn you can find users by
first name + last name very quickly. For example, you’ll find Terri
Hanson by searching for
te ha. Trailing whitespaces are ignored.
Under certain circumstances, running your ownCloud server on IIS could be at risk of data loss. To prevent this, follow these steps.
In your ownCloud server configuration file,
config.phpfile to read-only.
When you make server updates
config.phpmust be made writeable. When your updates are completed re-set it to read-only.
The Antivirus application offers three modes for running the ClamAV
anti-virus scanner: as a daemon on the ownCloud server, a daemon on a
remote server, or an executable mode that calls
clamscan on the local
server. We recommend using one of the daemon modes, as they are the most
Some ownCloud applications have the option to be enabled only for certain groups. However, when you select specific groups they do not get access to the app.
For security and performance reasons, file previews are available only for image files, covers of MP3 files, and text files, and have been disabled for all other filetypes. Files without previews are represented by generic icons according to their file types.
Because of limitations in
phpseclib, you cannot upload files larger
than 4GB over SFTP.
Setting user quotas to
unlimited on an ownCloud installation that has
unreliable free disk space reporting– for example, on a shared hosting
provider– may cause file uploads to fail with a
Not Enough Space
Available error. A workaround is to set file quotas for all users
In older versions of ownCloud, you could set an expiration date on both local and public link shares. Now you can set an expiration date only on public link shares, and local shares do not expire when public link shares expire.
Setting a user’s storage quota should be the equivalent of read-only, however, users can still create empty files.
Federated Cloud Sharing (formerly Server-to-Server file sharing) does not work with Shibboleth .
Windows Network Drive runs only on Linux servers because it requires the Samba client, which is included in all Linux distributions.
php5-libsmbclient is also required, and there may be issues with older
libsmbclient; see Using External Storage > Installing and
Configuring the Windows Network Drive application in the Enterprise
Admin manual for more information.
By default CentOS has activated SELinux, and the
httpd process can not
make outgoing network connections. This will cause problems with curl,
LDAP and samba libraries. Again, see Using External Storage > Installing
and Configuring the Windows Network Drive application in the Enterprise
Admin manual for instructions.
The SharePoint Drive application does not verify the SSL certificate of the SharePoint server or the ownCloud server, as it is expected that both devices are in the same trusted environment.
Shibboleth and standard WebDAV are incompatible, and cannot be used together in ownCloud. If Shibboleth is enabled, the ownCloud client uses an extended WebDAV protocol
SQLite is no longer an installation option for ownCloud Enterprise Edition, as it not suitable for multiple-user installations or managing large numbers of files.
