Working on Documents in the ownCloud Appliance

Creating and editing documents in ownCloud can be achieved with either Collabora or OnlyOffice. It’s your choice which one you prefer to use.

This guide covers the setup and update of the two office apps.

Here is an overview of the process:

  1. Access the Appcenter
  2. Install Collabora or OnlyOffice
  3. Update the App


Access with HTTPS using domain name is required. Add the IP address and the domain name of your appliance to your /etc/hosts file, or have it added to your existing DNS server, if you don’t want to use the Appliance as your DNS server.

If you encounter the error, “Failed to load the document. Please ensure the file type is supported and not corrupted, and try again.”, when trying to open documents, either restart the Collabora Docker container or the appliance.


First you have to get to the Appcenter. Here are the steps to do that:

  1. Connect to your appliance using IP address or domain name.
