bonjour

quand j'essaye d'installer des packages :
Code : Sélectionner tout - Visualiser dans une fenêtre à part
apt-get install kdessh
ils ne s'installent pas et je recois une message comme quoi il y a des "unmet dependencies" et que je dois résoudre cela en exécutant apt-get -f install

mais je recois alors le message suivant
