I don't want to reflash because I already know how to do that. But I don't know what was broken now or how to either fix it or prevent it from happening again. I think I could learn now a lot, maybe to opt out wrong packages when updating or upgrading and probably also learn where different kinds of stuff is stored and how to get it and install to right places.

Now I think this could be some kind of qt problem or then something else. But you mentioned the 'force install'. Have to say that from the way you use words makes it sometimes hard for me to understand correctly what you mean. Like now I'm not 100% sure do you suggest me to force install appdownloader or the other apps or not.

But I hope to learn how to make upgrade without breaking anything. Now I made the uppgrade and almost everything seems to work. It would not need a lot to learn how to prevent this to happen also to others.
