error upgrading to 15.10

[Antonio Mannocchi]

Impossibile calcolare l'avanzamento

Si è verificato un problema irrisolvibile durante il calcolo dell'avanzamento.

 I motivi possono essere:
 * L'avanzamento a una versione di pre-rilascio di Ubuntu
 * L'esecuzione dell'attuale versione di pre-rilascio di Ubuntu
 * Pacchetti software non ufficiali non forniti da Ubuntu

Se non vengono installati, segnalare il problema usando il comando «ubuntu-bug ubuntu-release-upgrader-core» in un terminale.

2016-01-07 06:14:30,444 DEBUG need_server_mode(): can not find a desktop meta package or key deps, running in server mode

Please install one of the following meta packages so the upgrade can be properly calculated.

10 # Distro contains global information about the upgrade
 11 [Distro]
 12 # the meta-pkgs we support
 13 MetaPkgs=ubuntu-desktop, kubuntu-desktop, xubuntu-core,
 14 xubuntu-desktop, ubuntustudio-desktop, mythbuntu-desktop,
 15 kubuntu-netbook, lubuntu-core, lubuntu-desktop, ubuntu-gnome-desktop

You probably want ubuntu-gnome-desktop.
