Impossible de corriger l'erreur "Impossible de résoudre les problèmes, vous avez mis en attente des packages endommagés."

Question

J'essaie d'installer python-pip. Mais j'obtiens l'erreur suivante:

root@w.x.y.z:~# apt-get install python-pip Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: python-pip : Depends: python-setuptools (>= 0.6c1) but it is not going to be installed E: Unable to correct problems, you have held broken packages.

Commencez par retirer complètement le python-pkg-resources en utilisant

 Sudo apt-get purge python-pkg-resources

Une fois terminé avec succès, première exécution

 Sudo apt-get -f install

ensuite

 Sudo apt-get install python-pip
