[MontelLUG] apt e GPG

[berno david]

Ho provato a fare un update delle backdoors ubuntu. Ma è da un po' di 
tempo che mi dà problemi con  la firma elettronica.
Ho googlagato un pochino, ma da quello che ho capito, apt dovrebbe 
reperire da se le chiavi GPG (in Fedora invece le dovevo installare a 
manina).
La posso richiamare nuovamente oppure devo modificare sources.list? Da 
notare che avevo modificato per un breve periodo tale file per 
aggiungere un paio di backdoors e rimuoverne alcune, e quando l'ho 
ripristinato è comparso l'errore.
Qualche dritta da darmi?
