[Bug 1084530] Re: package python-qt4 (not installed) failed to install/upgrade: short read on buffer copy for backend dpkg-deb during `./usr/lib/python2.7/dist-packages/PyQt4/QtGui.so'

[Ubuntu Foundations Team Bug Bot]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.  It seems that there was an error on your system when
trying to install a particular package.  Please execute the following
command, as it will clear your package cache, in a terminal:

sudo apt-get clean

Then try performing the update again.  This will likely resolve your
issue, but the failure could be caused by filesystem or memory
corruption.  So please also run a fsck on your filesystem(s) and a
memory test.  Thanks in advance!

[This is an automated message.  I apologize if it reached you
inappropriately; please just reply to this message indicating so.]
