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 package operation 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 not resolve your bug please set its status back to New. Thanks in advance!
