Thank you! I think I've identified the bug and a possible fix. I've
added the lxdm package to the bug, let's see if the

Oh, right, because of the dependencies. Of course. I should've
realized that, sorry!
Can try to fix the postinst script in place, like I suggested in my last
after which you should be able to complete the upgrade with
sudo apt-get -f install
sudo apt-get dist-upgrade
If that works, can you confirm that my suggested fix worked in that bug
If that doesn't work, there's still the alternative approach of removing
the lxdm package altogether. Since apt-get remove is unhappy, you can
use the lower-level dpkg tool (which doesn't enforce package
dependencies) to remove lxdm instead:
sudo dpkg --remove lxdm
after which apt-get -f install *should* be able to fix the dependency
situation, and apt-get dist-upgrade should be able to complete the

That's a very reasonable attitude, IMHO. The downside, of course, is
that you end up having to rely on random volunteers on the Internet to
solve any problems, or cash out for a support contract from Canonical or
some other support provider. ;-)
