Comment 2 for bug 272791

Thanks for your report.

The error in english roughly translated is:
=====
(Reading database ... for the time being installed 97776 files and directories.)
Unpacks the package language-pack-ru-base (from file .../language-pack-ru-base_1% 3a8.04 +20080527 _all.deb) ...
Replace a file from a set of language-pack-ru ...
dpkg: failed to process the option / var/cache/apt/archives/language-pack-ru-base_1% 3a8.04 +20080527 _all.deb (- unpack):
  Corrupted archive file system: corrupted package
=====

which means that your package is corrupted.

Could you please open a terminal and try the following :
sudo apt-get clean
sudo apt-get update
sudo apt-get install --reinstall language-pack-ru-base

Please tell us about the results.

Thanks.
