Errore aggiornamento nuova distribuzione Ubuntu

Ubuntu mi dice che è disponibile la nuova distribuzione Gutsy Gibbon.

Figo! ora mi aggiorno il sistema Faccio partire l'aggiornamento e mi si blocca già nella fase di "preparing the upgrade" dandomi una finestra con decine di errori.

Aggiornare alla nuova versione? Solitamente da errori quando nel file source.list ci sono repository non ufficiali. Prima di fare l'aggiornamento ti conviene cancellare tutto ciò che non era presente all'installazione.
