Comment 11 for bug 73062

once you run sudo apt-get update or have synaptic or any other package handler update the sources.list than you apt will not work. for me i was able to pin down the repo but adding one repo at a time and updating it. i didnt have to install any packages just update did it for me. removing the repos after runing apt-get update wont help. i was thinking about cleaning out the cache manully from apt to fix this but im tired of reinstalling this week if it doesnt work, so i may try that in a few weeks.
