[Linux-bruxelles] apt-get: unmet dependencies: try using -f

[Marc LEDENT]

Bonjour la liste,

Je renconrte actuellement un problème avec apt-get qui m'empêche de 
l'utiliser: Il me renvoie systématiquement le message qui suit:

Building Dependency Tree... Done
You might want to run `apt-get -f install' to correct these.
The following packages have unmet dependencies:
   xlibs-dev: Depends: libice-dev but it is not installed
              Depends: libsm-dev but it is not installed
              Depends: libx11-dev but it is not installed
              Depends: libxext-dev but it is not installed
              Depends: libxi-dev but it is not installed
              Depends: libxmu-dev but it is not installed
              Depends: libxmuu-dev but it is not installed
              Depends: libxp-dev but it is not installed
              Depends: libxpm-dev but it is not installed
              Depends: libxrandr-dev but it is not installed
              Depends: libxt-dev but it is not installed
              Depends: libxtrap-dev but it is not installed
              Depends: libxtst-dev but it is not installed
              Depends: libxv-dev but it is not installed
              Depends: xlibs-static-dev but it is not installed
E: Unmet dependencies. Try using -f.

J'ai voulu installer un package et suite à un plantage, je me trouve 
bloqué sur ce point.

Google était pas mon copain, man non plus, en plus personne ne m'aime.

Comment puis-je diagnostiquer efficacement ce problème?

Merci d'avance,
Marc Ledent
