I think the problem came from the many repos I had acivated and the many programs I had installed from them. But I reinstalled just a new system cuz this was a testing system anyway to see if I will uprage my main maschines the same way.
So I will setup a new machine with 12.04 - setup some repos, install some softweare and try to upgrade / reproduce the problem again. I will then post the results here. Thanks for your help.
