[Bug 996916] Re: postgresql packages in the removal blacklist making it hard to upgrade

[Robert sergo Dimanche]

la version 14.4 de Ubuntu ne peut pas etre rendu a la nouvelle version de Ubuntu. Il y a toujours un bug qui empeche la mise a niveau. Le message d'erreur est
:Impossible d'évaluer la mise à niveau

Un problème insoluble est survenu lors de la préparation de la mise à
niveau.

 Ceci peut-être dû à :
 * la mise à niveau vers une version de développement d'Ubuntu ;
 * la version de développement d'Ubuntu est actuellement utilisée ;
 * des paquets logiciels non officiels, non fournis par Ubuntu.

Si rien de tout cela ne s'applique, veuillez signaler ce bogue en
utilisant la commande « ubuntu-bug ubuntu-release-upgrader-core » dans
un terminal.

Title:
  postgresql packages in the removal blacklist making it hard to upgrade

Status in update-manager package in Ubuntu:
  Confirmed

Bug description:
  I have got this pop-up error message while updating from Ubuntu
  version 11.04 to 11.10:

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade:
  The package 'postgresql-plperl-8.4' is marked for removal but it is in the removal blacklist.

   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.
