I gave two options/debdiffs for fixing the bug above. For the common people, here's a temporary, but quick and painless way to fix it: 1) Close Software Sources 2) Download the file attached here (Ubuntu.info) 3) Replace the file in: /usr/share/python-apt/templates/Ubuntu.info 4) Open Software Sources now
