Have same problems with the apps - it’s on a production system - I have 5.0-1 errata235 - this is newer or I’m wrong? Is there a way to fix it? It’s still bad as some data changed and a roleback to an snapshot would be bad, especially as it would be need to be done again and again.
At first nextcloud was missing, now Jitsi is missing…
Hmm… after installing the errata, are you sure ?
Please send:
docker images
and
univention-app info
Thx
Before last updates nextcloud was working, Jitsi was working, I did only package updates and than Jitsi was gone, too.
The requested infos:
Thx, please send me you /var/log/univention/updater und appcenter.log via https://upload.univention.de/ and send me the number you get in the process.
You should safe the data manually and reinstall both after identifying the problem. I didn’t lost any data while fixing this error with other applications. But better a backup today than the one we’ve forgot yesterday 
Sorry for delay - now here’re the logs:
upload_ZrsN4w.txt
upload_GMMZrs.txt
There came a new update since this time, it’s already installed…
I was able to click “install” for nextcloud, but got this error while installing:
The container for 4.4/nextcloud=21.0.7-0 could not be started!

How would be the successful way to reinstall nextcloud on univention?
Thanks,
I’ve received the downloads. I can’t say yet why there is the message at arround 22-03-17 - 16:19:06 in the log:

But as I`ve suggested please remove the nextcloud container according to the article suggested and install nextcloud again.
All the best 
I reinstalled Nextcloud and it looks working again. Thanks. I hope it will persist and not run into same issue again.
I hope so too
Thanks for sharing.
