my /dev/loop0 is full its impossible to clean it with clean autoremove autoclean so I can't install KDE 12.04 can you tell me what I can do for it? thanks.

I've tried multiples informations before because a problem with a partition (that doesn't start on a physical sector boundary)
I have also problem with the kernel
Package: linux-image-3.2.0-83-generic-pae
Error: subprocess installed post-installation script returned error exit status 2

Package: linux-image-generic-pae
Error: dependency problems - leaving unconfigured

Package: linux-generic-pae
Error: dependency problems - leaving unconfigured
it's clear that everything is linked but I dont know how to fix it.

is it possible to refresh ubiquity?
