Title:
  impossible upgrade for old version to new version of ubuntu

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

Bug description:
  "An unresolvable problem occurred while calculating the upgrade:
  Le paquet « postgresql-plperl-8.4 » est marqué pour suppression mais il est dans la liste noire des suppressions.

   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"
