Re: purge de linux-image-2.6.14-2-k7

Pas d'autre message ?
Regarde le contenu de /var/lib/dpkg/info/linux-image*.postrm
Ben non pas d'autre message, aptitude s'arrête et c'est tout. Pour
essayer je l'ai laissé une nuit. Au réveil pas bougé, crtl-c pour
arrêter et tout va bien. Mais ce paquet est toujours là (enfin des
fichiers de conf) !
Quant à /var/lib/dpkg/info/linux-image-2.6.14-2-k7.postrm il existe
(ainsi que linux-image-2.6.14-2-k7.list vide) mais j'y comprends pas
grand chose. C'est un script qui doit se faire après désinstallation si
j'ai bien compris.
Que dois-je chercher dedans ?
Et si je les efface ?
Je vais les déplacer et tester, on verra bien.
Je le joint si ça peut aider.
