la funzione update non va piu' e mi rilascia la seguente dicitura:
E: dpkg è stato interrotto. È necessario eseguire "dpkg --configure -a" per correggere il problema.
E: _cache->open() failed, please report.

quindi vado su terminale e digito qunato sopra ottenendo la seguente sequenza:
sudo dpkg --configure -a *******************************************************************************************************************************************************************************************

Ora provo a riavviare ed effettuare di nuovo l'update ,ma nulla da fare, mentre se da terminale scrivo sudo apt-get update, pare che si aggiorni, ma nella grafica update i dati da aggiornare permangono.
Che fare? grazie
