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: ================================================================ Setting up wpasupplicant (0.7.3-6ubuntu1) ... 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 dpkg: error processing wpasupplicant (--configure): subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of network-manager: network-manager depends on wpasupplicant (>= 0.7.3-1); however: Package wpasupplicant is not configured yet. dpkg: error processing network-manager (--configure): dependency problems - leaving unconfigured dpkg: dependency problems prevent configuration of network-manager-gnome: network-manager-gnome depends on network-manager (>= 0.8.998); however: Package network-manager is not configured yet. dpkg: error processing network-manager-gnome (--configure): dependency problems - leaving unconfigured dpkg: dependency problems prevent configuration of ubuntu-desktop: ubuntu-desktop depends on wpasupplicant; however: Package wpasupplicant is not configured yet. dpkg: error processing ubuntu-desktop (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates its a followup error from a previous failure.

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.
