Title:
  Update from Ubuntu 11.04 to 11.10 does not work

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

Bug description:
  Trying to update Ubuntu 11.04 to 11.10. After downloading the new
  sources the following error pops up:

  Es konnte nicht ermittelt werden, welche Systemaktualisierungen
  verfügbar sind

  An unresolvable problem occurred while calculating the upgrade:
  E:Fehler: Unterbrechungen durch pkgProblemResolver::Resolve hervorgerufen; dies könnte durch zurückgehaltene Pakete verursacht worden sein.

   This can be caused by:
   * Upgrading to a pre-release version of Ubuntu
   * Running the current pre-release version of Ubuntu
   * Unofficial software packages not provided by Ubuntu

  If none of this applies, then please report this bug using the command
  'ubuntu-bug update-manager' in a terminal.

  Have already deactivated all sources manually, no change. Since I
  never had any pre-release installed and do not have any apparent
  package issues, I think this may be a bug.
