Starting at around 10:20 AM Pacific time on August 12th, 2015 my system started experiencing non-stop errors. Mozilla Firefox crashed, the OS started experiencing errors. I shut down the system completely and then booted back up. However, this didn't fix the problem. I tried applying the latest updates, but those won't install either and produced this crash report.

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!
