error during upgrade packages dpkg

[Gengis]

Release Ubuntu 8.04 Hardy Heron (italian language)

During normal application updates,
system begins to give errors

With EVERY packages,

this is my translation from italian of the message error appeared:

dpkg-deb: impossible create a directory: no file or directory
dpkg: error processing /var/cache/apt/archives/NAMEOFEVERYPACKAGE.deb (--unpack):
subprocess dpkg-deb --control returned error exit status 2

E: Sub-process /usr/bin/dpkg returned an error code (1)
Installation of a package failed

Probably important info:

- system downloaded correctly everything (i'm trying to upgrade 43 packages)
- simply don't install them
- few minutes before this upgrade, system crashed due of lack of electricity
   while was downloading the same upgrade packages

Thanks,
Paolo B

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Thanks in advance.
