Error during upgrade

[spacemarc]

Hi
My Ubuntu Feisty has some upgrade to do: after download of the
packages, I obtain this error:

/var/cache/apt/archives/smbclient_3.0.24-2ubuntu1.1_i386.deb:
unable to open the file with the list of file of package `initramfs-tools'
Errror of I/O
There are some errors processing:
/var/cache/apt/archives/smbclient_3.0.24-2ubuntu1.1_i386.deb:
E: Sub-process /usr/bin/dpkg returned an error code (1)


At moment, I'm unable to obtain all the upgrades (packages and
system): how can I do?
Thanks
