Nextcloud downgrade after UCS upgrade 4.4 to 5.0-1

Apps & App Center

#1

I updated a test system from 4.4 to the newest 5.x version and now nextcloud complains about a downgrade.
Is it correct that UCS 4.4 uses Nextcloud 21.0.7 and UCS 5.x is still on Nextcloud 21.0.5 and when will this change?

Kind regards

Haello,

I have recently installed a fresh 5.0-1 errata174 with nextcloud 21.0.7 as suggested packet. The same on my elder 5.0-0 errata174 installation.

Please post the following outputs:

univention-app info

univention-app list |grep --color -A2 -i next

ucr search repository/online/server

docker images |grep next

Hello Santiago.

thank you for the quick response.
Below you see the commands and their output.
I’ll try to run “univention-upgrade” next

Best regards

Ok. There is something else now. “univention-upgrade / upgrade.log” ends with:

Hello Mark,

as you can see in your docker docker images | grep next request you are dealing with two different nextcloud versions on your system :

docker.software-univention.de/nextcloud 21.0.7-0 1c36271a798a 7 weeks ago 1.18GB
docker.software-univention.de/nextcloud 21.0.5-0 1b9c0aa1ff67 2 months ago 1.18GB

So the question is what happend 7 weeks ago?

I don’t belive just trying to do an upgrade will change the problem. You should find out why this old , nextcloud container wasn´t removed.
appcenter.log and updater.log in /var/log/univention/ are helpfull informands for that kind of questions. You can backup your Nextcloud data in /var/lib/univention-appcenter/apps/nextcloud/data/nextcloud-data/. This might become helpful after getting rid of this situation.

Best regards

PS Please also send your:

dpkg -C

dkpg -C |–audit [ …] Check for damaged package(s).

Hello Santiago,

nextcloud 21.0.7-0 was installed 7 weeks ago (?) while I was running UCS 4.4. (at last it was running before the upgrade).
After the upgrade UCS 4.4 to UCS 5.0-1 nextcloud disappeared from the portal und the app center showed no installation of nextcloud. In the logs I found that the nextcloud data is still saved but something happend to the nextcloud app installation. (I assumed that the app was removed.) So I used the app center to install nextcloud again.

I have a tar file as backup of nextcloud-data

dpkg -C produces no output. So it looks like there is everything go with the installed packages.

Best regards

Hello Santiago,

it looks like I fixed it. Removing the nextcloud installation and installing it again should do the main part of the job. Then I had to deactivate und reload some apps inside the nextcloud. They showed up with a version of “0”.
All data looks good as far as I can see.

Before I tried the steps above I checked some other steps:

  • docker image prune -a gave me a better overview of used containers
  • docker container stop xxx and docker container rm xxx removed the nextcloud 21.0.7 container manually
  • after removing the nextcloud app (using the web interface) I checked docker again removing what still was found there from the nextcloud app.

Thanks and best regards

Hello Mark, we published a bug today which might be the root cause for this behavior. To avoid further problems please consider the workaround or wait till we’ve publishes an errata and follow the instructions.

#10

Hello @MarkD FYI
We have publised an errata which should avoid this from happening again.

#11

Hello Santiago,
thank you for this information. The errata is installed on my system now. We’ll see if the behavior occurs again. I am not sure how I can reproduce it.

Best regards
Mark.

#12

Update:
Thursday evening we installed the latest updates. (Jetzt UCS 5.0-1 errata317 and Nextcloud 23.0.4-0)
Some days later I was informed that the Nextcloud is not available. In UCS App Center Nextcloud was marked as ‘not installed’.
This commands solved the problem:

univention-app remove nextcloud
univention-app install nextcloud
univention-app install nextcloud

The second ‘install’ was necessary. I’ll try to find out more the next days.

Best regards
Mark.
