[Bug 840395] Re: package gcc-4.5 (not installed) failed to install/upgrade: short read on buffer copy for backend dpkg-deb during `./usr/lib/i386-linux-gnu/gcc/i686-linux-gnu/4.5/lto1'

[Brian Murray]

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 can be caused by filesystem or memory corruption.
So please also run a fsck on your filesystem(s) and a memory test.  If
this does resolve your bug please set its status to Invalid.  Thanks in
advance!

** Changed in: gcc-4.5 (Ubuntu)
       Status: New => Incomplete
