Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Bug reporting is mostly about finding & fixing problems thus preventing
future users from hitting the same bug.

I suspect a Support site would be more appropriate, eg.
https://answers.launchpad.net/ubuntu. You can also find help with your
problem in the support forum of your local Ubuntu community
http://loco.ubuntu.com/ or asking at https://askubuntu.com or
https://ubuntuforums.org, or for more support options please look at
https://discourse.ubuntu.com/t/community-support/709

(Your system needs some general housecleaning, eg. I see a PPA added
that supported only a single 12.10 release this should not have been
removed long ago)
