sto seguendo questa guida:
http://www.debianitalia.org/modules/...1&articleid=55

allora, creo i vari files, aggiungo il repository, aggiorno il database di apt installo libgnome2-0 ma all'ultimo comando mi da questo:

codice:
root@salentu:/home/ale# apt-get -t experimental install libgnome2-0

libgnome2-0 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 406 not upgraded.

root@salentu:/home/ale# apt-get install -t experimental gnome-desktop-environment

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  gnome-desktop-environment: Depends: gnome-themes (>= 2.8.2) but 2.8.0-1 is to be installed
E: Broken packages
root@salentu:/home/ale#

come risolvo?!..poi, è disponibile già gnome 2.10 per debian?!
