Title:
  Precise -> Trusty upgrade fails critically

Status in “ubuntu-release-upgrader” package in Ubuntu:
  New

Bug description:
  This will probably go down in history as the worst bug report I've
  ever filed but I'm a bit clueless here. I've actually repeated this
  twice with similar results and I know no more than I knew after the
  first failure. I'm certain though that we can't just let this one slip
  by because we'll recommend Precise -> Trusty upgrades when 14.04.1 is
  released - people are expecting it. And the Trusty HWE upgrade was
  disastrous for a number of users.

  Ultimately I'm going to need someone with more knowledge of the
  process to reproduce this so:

  #1: Install Ubuntu 12.04.4 which has the Saucy HWE kernel and X-stack
  #2: Update Ubuntu 12.04.4 and reboot when prompted
  #3: After reboot open Software Updater, accept the HWE upgrade, and reboot again
  #4: Perform the upgrade to Trusty using update-manager -d -c

  In my first test I was running 12.04.4 amd64 with the Trusty HWE and
  the Unity DE. Shortly after the upgrade began I got a crash report
  telling me that the update manager crashed so I selected relaunch and
  left the report button ticked but no report window ever appeared in
  Firefox. The upgrade process did continue however - it seemed to take
  much longer than usual but finally showed "errors were encountered
  while processing ubuntu-desktop", then it proceeded to search for
  obsolete packages which took a long time but never prompted me with a
  list of what it wanted to remove or gave any choice. The next thing I
  saw was the reboot to complete upgrade dialog so I did. Thereafter I
  was unable to load the Ubuntu session. TTY output was insane, for
  instance apt-get -f install produced a list to autoremove that was so
  long it scrolled off the screen. So I moved on to test #2.

  In my second test I was running Ubuntu 12.04.4 i386 with the Trusty
  HWE and the flashback (metacity) DE. Once again I got that update
  manager crash report but this time I did not select relaunch. I did
  once again leave send report ticked but no report was sent. The
  upgrade continued, once again taking much longer than usual, and once
  again saying "errors were encountered while processing ubuntu-
  desktop", searching for obsolete packages, and not displaying any
  prompt until telling me to reboot. This time I just closed without
  rebooting and filed this bug report.

  So I'm still booted into this desktop - luckily I already had Firefox
  open, but no apps will display, nautilus doesn't work, but I was able
  to open the terminal with Ctrl+Alt+T so I could file this. Once filed
  I'll dig around a bit and see if I can find anything else in the logs
  that might be useful.

  Sorry I can't be more helpful but I'm in over my head this time.
