I tried to upgrade my nextcloud version 30.0.11 to 31.0.5 . I ran the upgrade via:
sudo -u www-data php /var/www/owncloud/updater/updater.phar --no-backup
Finally the upgrade fails with an error when trying to delete a directory:
/var/www/owncloud/data/updater-octpturgf05m/downloads/nextcloud/apps/settings
When I rerun the upgrade the story remains the same but wit a different directory that failed to delete. And when I try to delete the directory that the updater could not delete by using sudo -u www-data rmdir <directorypath> this works just fine . I also checked that all files in the upgrader directory belong to the apache user which is www-data on my ubuntu 24.04 system. For now I can return back to 30.0.11 because the cloud is running in a virtual machine that I snapshotted before upgrading, so I can start again from a running 30.0.11 system.
Rerunning updater.phar after it failed one time it fails again in the next run in the same step but for another directory. I tried 3 times and got each time an error for a different upgrader dir in each try:
Could not rmdir /var/www/owncloud/data/updater-octpturgf05m/downloads/nextcloud/apps/settings
Cloud not rmdir /var/www/owncloud/data/updater-octpturgf05m/downloads/nextcloud/apps/user_ldap/lib/Notification
Could not rmdir /var/www/owncloud/data/updater-octpturgf05m/downloads/nextcloud/apps/files_versions/lib/Migration
The given directotry was always empty and could easily be remove by running
sudo -u www-data rmdir <path>
I also checked that there is enough free space on the filesystem.
Its really strange this error, no idea whats going on.
The following log is from /var/log/owncloud and shows the relevant part where the upgrader fails in one run:
