Nextcloud Wartungsmodus nach Upgrade

Hallo,
ich habe gestern über den Nextcloud Hub auf Version 23.0.6-0 geupdatet.
Jetzt kommt mein Nextcloud über den Wartungsmodus nicht mehr hinaus. Vorher lief es perfekt.
In der config habe ich den maintenance auf false gesetzt, jedoch leider keine Änderung.
Kann mir da bitte jemand helfen?
Vielen herzlichen Dank!!!

I’ve got no pre-update snapshot…

In the long run, you should think about a solution (virtualization) that allows you to quickly and easily create snapshots of your systems to undo a failed update in such cases.

Maybe this article will help:

The search brings up some posts with similar context. Have you looked at these?

I tryed a lot of things:
root@ucs:~# univention-app shell nextcloud sudo -u www-data php /var/www/html/occ maintenance:mode

But this will not work…

Administrator@home:~$ univention-app shell nextcloud sudo -u www-data php /var/www/html/
occ maintenance:mode

Did you install Nextcoud from Univention App-Center?

Is the Nextcloud instance running?

docker ps

should show you the running Nextcloud instance.
Otherwise something went wrong with the upgrade. Check the latest logfiles in

/var/log/apache/
/var/log/univention/

docker ps

The log i try to check…

I installed it with the official update by univention.

there are many logs…
Please help me…!

Solved!!!
Now it works!
The key was to put in “su” into the terminal and then I get the permission…
How easy…
