[Bug 1068594] [NEW] Failed to upgrade from 12.04 to 12.10, I was left with an unusable system

[Peter Velosy]

Public bug reported:

When upgrading from 12.04 to 12.10 using update-manager and the kfki
server from Hungary, I was confronted with the error "subprocess new
pre-removal script returned error exit status 1" for debconf, along with
the same error for python3, libpam-modules and lsb. The upgrade
terminated with a message like "Process aborted, too many errors", then
the Restart button was shown, but I was presented with an unusable OS
that boots into a black screen, and where repair mode didn't work either
(it simply did nothing after running fsck). I had to reinstall
everything from scratch.
