[rseek]

manually upgrading with sudo -u www-data php occ upgrade did the trick

[rullzer]

@rseek I'm glad it is fixed. But still weird error. I'll close this for now. If anybody runs into it again maybe we can debug...

chroot thing?

[jult]

Something similar here (manually upgrading with sudo -u www-data php occ upgrade did NOT fix it..)
My nc update remains in Maintenance mode. Quite annoying. I updated through the web GUI.
Relevant logs, stripped of signatures etc.;
http://afluisterland.nl/uptown/updater.txt
http://afluisterland.nl/uptown/nextcloud.txt

After manually switching off Maintenance mode, I get;
`# sudo -u www-data php occ upgrade

You may use your browser or the occ upgrade command to do the upgrade
