Internal server error after upgrade using docker-compose pull

I recently upgraded my nextcloud from 18.0.4 to latest docker image with docker-compose pull.
It resulted in an Internal Server Error screen on logon.
The first problem that I saw was that all file ownerships had been changed to root:root in the data dir, which is fixed, but the internal server error message remains as seen below.
On top of that there is one user who havent signed on yet that occ files:scan say don’t have write permissions to her home folder, even though it’s the same permissions and ownership as all the other users…
At this moment the Internal Server Error is css formated, but at times through my try to fix journy, it has been raw format…

Some things I have tried:

tried solutions

docker exec --user www-data cloud-container php occ files:scan --all -vvv
docker exec --user www-data cloud-container php occ files:cleanup
docker exec --user www-data cloud-container php occ maintenance:mode --off
docker exec --user www-data cloud-container php occ db:convert-filecache-bigint
docker exec --user www-data cloud-container php occ db:add-missing-indices
docker exec --user www-data cloud-container php occ files:scan-app-data
docker exec --user www-data cloud-container php occ maintenance:repair

Remove file locks
docker exec --user www-data cloud-container php occ maintenance:mode --on
docker exec -it mariadb mysql -p -e ‘DELETE FROM oc_file_locks WHERE 1’ nextcloud
docker exec --user www-data cloud-container php occ maintenance:mode --off

Change permissions for data folder…
docker exec --user www-data cloud-container chown -R www-data:www-data /var/www/html

Greateful for tips on where to go next since I’m lost…

Update:
When I go to the url in private mode, I get a login screen. But after login the Internal Error page comes again with the same error as before.
I have tried to disable apps, including user_ldap but to no vail… This problem is beginning to frustrate me.

Update 2:
I tried to make a new nextcloud image to see if it was something with the upgrade that failed. It seems that this new session also wants the ownership of the files to be root:www-data. Is there something going on with this update that requires updateing ownerships of the whole data dir??

Please post the output of your http(s)://[your_nextcloud_domain_or_ip]/status.php

status.php: {"installed":true,"maintenance":false,"needsDbUpgrade":false,"version":"19.0.3.1","versionstring":"19.0.3","edition":"","productname":"Nextcloud","extendedSupport":false}

So I guess i upgraded a whole version then.

Update: Since changing all ownerships to root:www-data I have ran occ scan-app-data, same error. Removed js folder from appdata and rerun scan-app-data, same error. Truncate oc-filecache table in the database, same error. Ran maintenance:repair, maintenance:update:db, maintenance:update:js, maintenance:update:htaccess, same error.
Is there nobody out there with some clue on whats going on?

After running a new instance of nextcloud again and again…
The container has www-data and group in apache2 envvars and they are listed as uid and gid 33 as before. But when the nextcloud installation is running it creates the appdir and admin dir with root:www-data ownership and they are created empty… Dirs have permission 660, so should not be a problem as long as the group is correct…

dock:/var/docker/nextcloud2# docker exec --user www-data nextcloud2 ps aux

Can it be that the root apache process is the one that creates the first folder and the other ones dont get access to create in these or something like that?

Solved!
It had nothing to do with docker or nextcloud.
For some reason, the NFS share that the data folder is mounted on created all files with the wrong ownership.
When that was fixed, I rerun occ files:scan-app-data and I was in!
I have no idéa why since I have not changed anytning on either the server or the client side for the share since the first install of nextcloud… But now it’s fixed and I can start fixing all the problems that I caused during the 3 week long trouble shooting…
