Forum Ubuntu-it

Ciao a tutti,
ho appena installato sul mio acer aspire one l'ultima versione di ubuntu (la 11..), ma non riesco a fare nessun aggiornamento di sistema ne tantomeno installare qualsiasi programma da Ubuntu Software Center, mi dice "Failed to download package files" e "Check your Internet connection." ma ovviamente la mia connessione funziona benissimo anche perchè andando ad installare i programmi da terminale tutto funziona. che fare?
Grazie

Dai un da terminale e riporta il risultato

Reading package lists... Done

Oltre a "Failed to download package files" ti spunta qualcos'altro? Tipo un indirizzo o un pacchetto in particolare?

Pare e dico pare che si sia tutto risolto.
Suppondo dopo l'ennesimo aggiornamento da terminale si sia sistemato qualcosa....

Grazie per la collborazione.
