apt-get / dpkg crash

[Bertrand Caplet]

Hi, I tried to update my system using apt-get update and I got a bug while updating "cups".
Now when i'm trying to do an apt-get -f install or any try to install a packet It freeze at 95% of reading the database of packets and it says "dpkg : erreur fatale irréversible, abandon :
 échec dans « buffer_read(fd) » : liste des fichiers du paquet « cups »: Input/output error"
In english it may be like that : "dpkg : reading fatal error, abort.
failed in "buffer_read(fd)" : list of the files of the paquet "cups" : Input/output error".

This symptom is normally caused by file system corruption.
