package initramfs-tools 0.103ubuntu0.2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

I upgraded my Linaro Ubuntu ARM PC from 12.04 to 12.11 and now I have always this bug problem :/

Now I am always running into an error while upgrading and so on.
I get the following messages trough ssh while upgrading:

The system itself is running well, but I can not use the unity desktop and all the graphics around.
I can only login trough ssh.

Please help me to install the correct version of "initramfs-tools".
