Title:
  do-release-upgrade from 12.04 LTS to 12.10 fails

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  root at dev:/etc/update-manager# cat release-upgrades
  # Default behavior for the release upgrader.

  [DEFAULT]
  # Default prompting behavior, valid options:
  #
  #  never  - Never check for a new release.
  #  normal - Check to see if a new release is available.  If more than one new
  #           release is found, the release upgrader will attempt to upgrade to
  #           the release that immediately succeeds the currently-running
  #           release.
  #  lts    - Check to see if a new LTS release is available.  The upgrader
  #           will attempt to upgrade to the first LTS release available after
  #           the currently-running one.  Note that this option should not be
  #           used if the currently-running release is not itself an LTS
  #           release, since in that case the upgrader won't be able to
  #           determine if a newer release is available.
