When I try to upgrade linux-image-3.0.0-26-generic I get following problems:

dpkg-deb (subprocess): data: internal bzip2 read error: 'DATA_ERROR'
dpkg-deb: error: subprocess <decompress> returned error exit status 2
dpkg: error processing /var/cache/apt/archives/linux-image-3.0.0-26-generic_3.0.0-26.42_amd64.deb (--unpack):

E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install.  Trying to recover:

dpkg: dependency problems prevent configuration of linux-image-generic:
 linux-image-generic depends on linux-image-3.0.0-26-generic; however:
  Package linux-image-3.0.0-26-generic is not installed.

I don't know why this happens to me; earlier upgrades always worked without problems.

Does anybody know how to fix this?
