  2. enter a valid FQDN inside the Host name field

  3. enable Let's Encrypt option accordingly to your needs

Nextcloud update/upgrade procedure may disable the apps to avoid incompatibility problems. Server logs keep track of which apps were disabled. After a successful update/upgrade procedure you can use the Applications page to update and re-enable the apps.

User list#

All users are listed inside the administrator panel of Nextcloud using a unique identifier containing letters and numbers. This is because the system ensures that there are no duplicate internal user names as reported in section Internal Username of Official Nextcloud documentation.

Collabora Online#

First, install and configure a Collabora Online instance.

Then, access the Settings page of Nextcloud module.

You will find an option named CODE server host name. Select one of the existing Collabora instances or enter a domain of another Collabora installation.

The Collabora instance will be accessed using HTTPS protocol, so remember to disable the Verify TLS certification option if the Collabora does not have a valid TLS certificate.

Finally, click the Save button. You will now be able to edit documents directly inside Nextcloud.

Data retention policy#

When it comes to account deletion in Nextcloud, a specific data retention policy is employed based on the user’s account origin:

  • if the account originates from the LDAP account provider, its data isn’t subject to automatic removal. You can find detailed information about this policy in the documentation: LDAP Cleanup.

  • in the case of accounts stored within the internal Nextcloud database, their associated data is immediately and automatically removed upon deletion. Further insights can be accessed here: Deleting Users.
