[PROBLEM] Error everytime i try to upgrade Python

[alfaromeo]

Hallo guys!

I had the same issue and tried the hint from your first reply mk01...

But now I also can't connect to SSH and the system hangs during shutting down.

I want to fix it now with your other tips, but how should I do that?? Where can I enter these commands? I can only navigate through XBMC. As soon as I exit XMBC it gets stuck on the shutting down screen

I managed it to delete "splash" from cmdline.txt and now I can exit XBMC and I can enter code with my keyboard. But nothing happens when I do that

Can you please help me?!
I just set up the system perfectly and don't want to wipe it


EDIT: I also cannot access my NAS Drive through MSB anymore -.-
