Hi all! well, last time I did a dist-upgrade , the system hanged, and even the "magic keys" didn't answered, so I had to reboot the system.
After that, there was one package that i couldn't upgrade, nor install, nor uninstall. (xserver-xorg to be precise) So after somme googling, I tried to edit /var/lib/dpkg/status /var/lib/aptitude/pkgstates and remove the entries of xserver-xorg I also removed /var/lib/dpkg/info/xserver-xorg.* (preinst, postinst, prerm, postrm, and so on) but the system still won't install the package. It always failed during the preinst script it seems : root # dpkg -i /var/cache/apt/archives/xserver-xorg_6.8.2.dfsg.1-9_i386.deb (Lecture de la base de données... 134036 fichiers et répertoires déjà installés.) Dépaquetage de xserver-xorg (à partir de .../xserver-xorg_6.8.2.dfsg.1-9_i386.deb) ... dpkg : erreur de traitement de /var/cache/apt/archives/xserver-xorg_6.8.2.dfsg.1-9_i386.deb (--install) : le sous-processus pre-installation script a retourné une erreur de sortie d'état 1 Des erreurs ont été rencontrées pendant l'exécution : /var/cache/apt/archives/xserver-xorg_6.8.2.dfsg.1-9_i386.deb ( it's in french, but basically, it says that there was an error during dpkg during preinst script with an error or exit code 1) Well, the questions are : - How to make the system believe that the package isn't (or is) install, in order to remove and reinstall it properly - Is there a way to "run the dpkg process" step by step by hand with only some basic commands as cp, rm, mv, mkdir, .... to see where there is a problem - any other idea? - Do I need to reinstall the whole system? I thank you all for any help! I already tried a lot of google but i couldn't find a solution to this problem. I also don't mind to read a lot of useful stuff if anybody has some ideas. Thanks a lot for any useful link or idea!!!
