[gull] comportement incomprehensible de ``aptitude''

[Cedric BRINER]

bonjour,

je viens de faire une installation fraiche d'une machine a l'aide de fai (Fully Automatic Installer).
Cette installation utilise uniquement aptitude pour la gestion des paquets, afin qu'aptitude aie
une base de donnee coherente.

Suite a ca, je desire installer fai sur cette meme machine (juste la partie client):
aptitude -R install fai

bizarre..
je fouille un peu et me rend compte que:
  aptitude update
  aptitude upgrade
  aptitude dist-upgrade
ne me propose de supprimer les paquets mentionnes ci-dessus !

de plus, si j'installe fai server
aptitude install -r fai

il perd tout d'un coup son envie de desinstaller la moitie des paquets.

vient maintenant le temps des question:

1) Une idee du pourquoi de ce comportement ?

de plus, les paquets qu'il desire supprimer sont bien des paquets installer
de maniere automatique (ce qui donne un point positif pour aptitude)


2) Qqun connaitrait-il un programme (graphique :) ) qui permette de se deplacer
dans les dependances tant ascendante que montante.

3) existe-t-il un moyen de calculer:
gnome-desktop-environment - (mozilla-browser, epiphany-browser)



Merci d'avance de vos eclaircissements.


Cedric
