[Bug 1492266] Re: upgrade from 14.04.2 to 14.10 hangs on calculating upgrades

[Brian Murray]

Thank you for taking the time to report this bug and helping to make
Ubuntu better. The release upgrade process will now try to upgrade from
14.04 (Trusty) to 15.04 (Vivid) as 14.10 (Utopic) is End of Life. Could
you please try the upgrade process again and if it fails open a new bug
report following the same process you used to open this one? Thanks in
advance!

Title:
  upgrade from 14.04.2 to 14.10 hangs on calculating upgrades

Status in ubuntu-release-upgrader package in Ubuntu:
  Incomplete

Bug description:
  Upgrading 14.04.2 to 14.10 hangs on "Calculating Upgrades".  I have ran the following commands numerous times and in numerous orders:
  sudo apt-get autoremove
  sudo apt-get dist-update
  sudo apt-get update
  sudo apt-get upgrade

  I have even deleted the "apt.log" file in /var/log/dist-upgrade/apt.log after finding that in a forum.
  Running grep ERROR /var/log/dist-upgrade/main.log returns:
  ERROR Dist-upgrade failed: 'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'

  Package manager says all packages are up to date.
