Ok, got the upgrade running (same machine as i am writing this message on now). Apparently some "unity" packages sneaked into the system. As I don't need those, I removed them and everything seems to be fine now. However I still don't know what packages exactly are causing this problem. This would be very helpful for users to know. Isn't there a better way to show what actually is causing the problem?
