Problems after Updating OwnCloud Server on Ubuntu 14.04

9.1.x

Hallo

A few month ago I installed OwnCloud on my Ubuntu 14.04 server with the ppa.
Today I updated my server with apt dist-upgrade and a new server version was installed.
After that I could not access until I disabled maintenance mode manually:
sudo -u www-data php occ maintenance:mode --off
Now I get the message:
Exception: Updates between multiple major versions and downgrades are unsupported.
Update failed

There is a link for this problem, telling my to install first a skipped mayor update. But I am not sure which version I have.

Steps to reproduce
Install old version of OwnCloud and update it with you system (ppa)

Expected behaviour
Should work or show version of old installation

You can get your previous version from the config/config.php which isn't updated yet.
