Same issue here, I first upgraded from Ubuntu 16.04 to 18.04 then used the upgrader in nextcloud web to upgrade from 13 to 14. I now have exactly the same issues. My mobile nextcloud app although still works fine. So I guess it has something to do with the changes from PHP 7.0 to 7.2.

I'm still stuck. Did you already found a solution?

For me the problem was file permissions and usually it is specifically the data directory.

[rmader]

Since today I get the exact same error. Already reset the permissions, upgraded to latest point release.... @stone212, was anything special about you setup to trigger this?

[stone212]

@treba123 Nothing special but I found the problem was that the file permissions on the data directory were wrong. Do you have a data directory? Are the file permissions correct? I have this note written down under "Nextcloud":

cd /var/www
chown -R www-data:www-data nextcloud
find nextcloud/ -type d -exec chmod 750 {} \;
find nextcloud/ -type f -exec chmod 640 {} \;

[rmader]

@stone212: thx for the answer! Yeah that was what I ended up doing, too, on program and data directory. Didn't directly work, but at some point I rebooted again and...well, now it works again :)

The thing is, my data directory is on a smb share, mounted via systemd-automount. So I thought maybe somewhere down that road something is wrong.

cd /var/www
chown -R www-data:www-data nextcloud
find nextcloud/ -type d -exec chmod 750 {} \;
find nextcloud/ -type f -exec chmod 640 {} \;

Of course helpful, this is a perfect fix

This one has worked for me.
Saved my time boy, thank you.
