[Linux-Biella] Jaunty non si aggiorna da un mese, ho dei sospetti

[Simone Linux]

Da quando ho installato jaunty ho fatto mi ha proposto un solo
aggiornamento, poi non mi ha più proposto nulla...mi sembra strana sta
cosa...
Anche manualmente dal gestore aggiornamenti mi dice che è aggiornato...BOOOOH!
A voi ultimamente ha proposto aggiornamenti?

Ho controllato i repository dell sources.list ma mi sembrano corretti....
Vi incollo il contenuto:
