[SOLVED] Upgrade stuck after downloading the packages

[simonszu]

I have a following problem with upgrading the system via SSH.

After i made an apt-get update, i tried apt-get upgrade as well as apt-get install xbian-update.

Both have the following problem: The process downloads the packages, and tells me how much it has downloaded.

After that, nothing happens. The SSH is completely frozen, i can't ctrl-c the process, nor kill the session with ~.

The pi also doesn't accept new connections. The only solution is to pull the plug and reboot it. Needless to say, the upgrade isn't installed then.

During the freeze, the TV GUI is frozen, too. I can move the mouse, but the buttons won't respond, and the clock does not count.

Help me, please. How can i upgrade my xbian?
