Apt suse 9.2: bad magic

[Netfranz]

Ciao a tutti
col passaggio a Suse 9.2 ho iniziato a usare apt; c'e' pero' un piccolo problema: quasi sempre, ogni volta che faccio upgrade, alcuni pacchetti (se non tutti) danno error: bad magic. L'errore sparisce re liancio upgrade sugli stessi, diciamo, il giorno dopo... nessuno ha suggerimenti in merito?
