Title:
  update-manager fails to display an error message

Status in “update-manager” package in Ubuntu:
  Fix Released
Status in “update-manager” source package in Oneiric:
  Fix Released
Status in “update-manager” source package in Precise:
  Fix Released

Bug description:
  = Impact =

  Users of update-manager will not receive an error message in the event
  that there is an error but instead a Traceback from the error dialog
  window.  This isn't very helpful and prevents users from knowing what
  went wrong.

  = Test Case =

  1) run 'update-manager -d' in a terminal
  2) disconnect my network connection
  3) click upgrade to 12.10
  4) see release notes error message and click 'upgrade' again

  You'll then receive the Traceback described below ending in
  'RunTimeError: unable to get the value'.

  For Oneiric to recreate this you'll need to disconnect your network
  connection after viewing the release notes - otherwise you will see a
  'could not donwload release notes' error.

  = Original Description =
  I tried updating Kubuntu 11.10 to 12.04 (beta) with
  $ update-manager -d

  but I did receive error in console:

  authenticate 'precise.tar.gz' against 'precise.tar.gz.gpg'
  extracting 'precise.tar.gz'
  Traceback (most recent call last):
    File "/usr/lib/python2.7/dist-packages/UpdateManager/UpdateManager.py", line 1099, in on_button_dist_upgrade_clicked
      fetcher.run()
    File "/usr/lib/python2.7/dist-packages/UpdateManager/Core/DistUpgradeFetcherCore.py", line 284, in run
      _("The error message is '%s'.") % e.strerror)
    File "/usr/lib/python2.7/dist-packages/UpdateManager/DistUpgradeFetcher.py", line 41, in error
      return error(self.window_main, summary, message)
    File "/usr/lib/python2.7/dist-packages/UpdateManager/Core/utils.py", line 404, in error
      d.window.set_functions(Gdk.FUNC_MOVE)
  RuntimeError: unable to get the value

  I belive that line 284 DistUpgradeFetcherCore.py is error handling routine so probably root error did occured few lines earierl and stack trace was printed for bug in method for displaying errod dialog.
  Running update-manager with sudo did help with this issue, but it failed later and prompted me to report a bug.
  Using
  $ do-release-upgrade -m desktop -d
  gives same result as sudo update-manager

  Wystąpił nierozwiązywalny problem podczas obliczania aktualizacji:
  E:Error, pkgProblemResolver::Resolve generated breaks, this may be
  caused by held packages.

  I did tried manually turning off any non standard repositories but it
  did not help.

  Please let me know if you need any aditional logs/configs.
