I tried the upgrade to 12.04 LTS (beta) on 2012-03-16, and experienced
the same problem, and Update Manager got stuck with "wpasupplicant" and
its dependencies "network-manager", "network-manager-gnome" and "ubuntu-
desktop" left uninstalled.
I then tried to fix the problem manually by using "sudo apt-get -f
install", and saw the following:

Hmm... looks like a problem with "/lib/init/rw" to "/run" migration, which I
cannot quite remember when it happened on Ubuntu.
On my computer, I see:
$ ls -l /lib/init/rw
lrwxrwxrwx 1 root root 4 Oct 17 08:11 /lib/init/rw -> /run
Checking wpasupplicant postinst script
/var/lib/info/dpkg/wpasupplicant.postinst, Lines 27-36:
# Migrate existing sendsigs omission pid files to /run
if [ -d /run/sendsigs.omit.d/ ] && \
[ -d /lib/init/rw/sendsigs.omit.d/ ]; then
for f in
/lib/init/rw/sendsigs.omit.d/wpasupplicant.*.pid
do
if [ -f "$f" ]; then
mv "$f" /run/sendsigs.omit.d/
fi
done
fi
The "mv" command above fails because /lib/init/rw is a symlink to /run,
hence the error:
mv: `/lib/init/rw/sendsigs.omit.d/wpasupplicant.wpa_supplicant.wlan0.pid'
and
`/run/sendsigs.omit.d/wpasupplicant.wpa_supplicant.wlan0.pid' are
the same file
As a quick workaround, I changed
mv "$f" /run/sendsigs.omit.d/
to
mv "$f" /run/sendsigs.omit.d/ || true
so that the error is ignored, and a new run of "sudo apt-get -f install"
now completes.
Hope this helps,
Anthony
