Potential fix ONLYOFFICE/onlyoffice-nextcloud#830 (comment)

Potential fix ONLYOFFICE/onlyoffice-nextcloud#830 (comment)

I'm not sure how to fix it. I tried removing onlyoffice and installing onlyoffice V8.1.0, but it seems neither worked for me.

[nemchik]

Can you try removing onlyoffice entirely and not installing another version and see if things run?

It could be a bug with onlyoffice that they need to fix. If things still don't run even when you remove onlyoffice entirely then it could be a bug on our end, or maybe still something else.

Same problem here. Last update was 5/27 (v 26.02 I think). Updated today, and I'm getting the same message as @squallxb1983
Running on an Alpine server (x86-64), Nextcloud and Mariadb installed and updated using docker-compose.
I don't have the OnlyOffice App installed, so that is not my issue.

[nemchik]

Post your log. Even if it's the same error, there may be context around it.

It appears to be a Mariadb error. Nextcloud can't connect to the database, per log above. I ran database check on Mariadb
mariadb-check -u root -p<PASSWORD> -c -A # check all databases for errors
and got this:

mariadb-check: Got error: 2002: Can't connect to local server through socket '/var/run/mysqld/mysqld.sock' (2) when trying to connect

I updated the Mariadb container at the same time as the Nextcloud update, as I've always done, but this time it seems there is an issue. Any pointers on how to fix Mariadb appreciated.

Edit: I followed instructions detailed here linuxserver/docker-mariadb#125 and here https://github.com/linuxserver/cstate/blob/2505217ea6d06b00a1b413d44108c47f0a6cccee/content/issues/2023-05-28-mariadb.md to roll back Mariadb to 10.6.13.
Now Nexcloud displays in Maintenance mode, so the problem was Mariadb. However I do still have a different problem to solve with Nextcloud after getting past the error reported above.

[Italia38]

Fixed the issue on my Nextcloud instance and was able to upgrade to v27. After fixing the Mariadb issue (see above) and pinning to v 10.6.13, Nextcloud appeared in Maintenance mode due to some database errors. The fix was to change the line in the config file to turn maintenance mode off, then was able to log in to Nextcloud via the web interface. In Administration, ran checks and it showed database related errors, there were four outdated tables. Ran docker exec -it nextcloud occ db:add-missing-indices, then updated /nginx/site-confs/default.conf and /nginx/nginx.conf, restarted the container, and all is updated and functioning properly so far.

I gave up and installed nextcloud AIO instead. Then migrated all the data to AIO, now everything runs smoothly as it should be. The management in AIO is also easier and the new backup function is very useful.
