package openjdk-6-jre-headless 6b18-1.8.1-0ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

I believe that this package is preventing other things from installing. I'm not exactly sure how, but this error has come up a few times whenever I have tried to either install or upgrade a program. It still baffles me.

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!
