Are you using external storage, if yes which one: No

Are you using encryption: No

Are you using an external user-backend, if yes which one: LDAP + SAML

Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade

  [Symfony\Component\Console\Exception\CommandNotFoundException]  
  There are no commands defined in the "ldap" namespace.

https://github.com/nextcloud/server/pull/6177

And it was fixed in https://github.com/nextcloud/user_saml/pull/145 but not yet published: https://apps.nextcloud.com/apps/user_saml

Is there any simple way to fix this without restoring?

Apply this patch to the user_saml app: https://github.com/nextcloud/user_saml/pull/145.patch

[bocan]

Many thanks. That allowed it to upgrade properly.

[frake65]

Sorry for this noob question, but where can I find this file in my directory structure? - It's not under nextcloud/lib...

[frake65]

ok, seems I have found the file - problem was, it's spelled lowercase. Still got problems after completing the update process...

[MorrisJobke]

New version is published in app store and should be pulled on the next update automatically or manually via the app management.

Update from 12.0.2 to 12.0.3 via Update-Channel 'stable' still results in:
PHP Fatal error: Class OCA\User_SAML\UserBackend contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (OCP\Authentication\IApacheBackend::getLogoutUrl) in /var/www/nextcloud/apps/user_saml/lib/userbackend.php on line 34

Solution: application of patch: https://github.com/nextcloud/user_saml/pull/145.patch

enables 'Update successful' via
sudo -u www-data ./occ upgrade

(subsequently disable maintenance mode in ./config/config.php:
'maintenance' => false,)

I have the same problem as yours @schmidchr

Updating the SAML app manually before upgrading via the apps interface should resolve this, there seems to be a bug in the updater that it is loading the app to early.

That is because it is an authentication type app. This could only be fixed by first upgrading user_saml and then run the server upgrade :/

We look into resolving such things in the future. Some work has been done in the caniupdate app: https://github.com/nextcloud/caniupdate
