Hello
i got a problem after update/upgrade, it doesn´t matter if i try it via xbian config or by sudo -i and:

apt-get clean
apt-get update
apt-get upgrade

this is the message i get:

Preconfiguring packages ...

E: Sub-process /usr/bin/dpkg returned an error code (2)

What can i do?
I use Xbian RC2 and Gotham 13.1 on a Raspberry.

Thanks for your Help.
