Stuck in update 8.2 --> 9.08 via Updater

I did an update via updater from OC 8.01 to 8.02 and everything went smoothly. Then I did the same to upgrade to 9.08 but I got stuck with the following message (see screenshot). I can turn of the service mode but then I get the update page again and I'm stuck in a loop.

What can I do?

my OC is hosted at

Looks like exactly the same as in [1]. There you will find a possible solution.


Thanks a lot! Didi it!
