gestionnaire de mise à jour

[Aesclepios]

Bonjour à tous.

Après mise à jour intrepid vers jaunty sans problème, la mise à jour
dans le gestionnaire de mise à jour se fait normalement pour les mises à
jour "recommandées".

Le gestionnaire me propose une mise à jour pour les paquets
- brasero
- gstreamer0.10-plugins-bad

Or il est impossible de les cocher et de faire les mises à jour de ces
paquets.

La question est pourquoi ? Est ce que ce sont des versions pour
intrepid, des versions instables... mais alors pourquoi le gestionnaire
les propose t'il ?
