Thank you for taking the time to report this bug and helping to make Ubuntu better. Reviewing your log files attached to this bug report it seems that a package failed to install due to a segmentation fault in the application being used for the package installation process. Unfortunately, this bug report isn't very useful in its current state and a crash report would be much more useful. Could you try recreating this issue by enabling apport to catch the crash report 'sudo service apport start force_start=1' and then trying to install the same package again? This process will create a new bug report so I am marking this one as Invalid. Thanks again for helping out!
