Oh ye of little faith in the Great God Ubuntu who will never let you
down provided you Believe in Him.
I have the luxury that, being retired, this is all just a hobby for me
and if things get messed up then it just adds to the challenge and
helps to prevent (or at least delays) atrophy of the brain.
Everything important is backed up of course (on disk that is, not the
brain, unfortunately).
I uninstalled the packages that synaptic thought should not be there
in the first place, purged all the ppas and
sudo sed -i 's/quantal/raring/g' /etc/apt/sources.list
sudo update && sudo dist-upgrade
Rebooted and everything seems to be working except
squid-deb-proxy-client so I have disabled that for the moment while I
determine whether anything else is giving problems.
I see one other malfunction, in System Settings > Mouse & Touchpad I
have the General and Touchpad sections but the Mouse section with
Mouse Pointer Speed is entirely missing.
I would still like to know how those packages got installed in the
first place however. A number of them seemed to be to do with
Evolution so I wonder whether an Evolution upgrade at some point left
orphan packages lying about. I did install 12.10 in August while it
was still pre-release so that may be the cause. Autoremove did not
see them however.
