title: Incorrect sources.list causing apt-get update to fail Ubuntu 13.04
body: <p>I was trying to install ruby using the rvm and it was failing due to a problem with apt-get update. I discovered that this is caused by problems with the sources.list file in the etc/apt directory. I tried to use this <a href="http://blog.ubuntu-tweak.com/guide/how-to-fix-the-source-list-files" rel="nofollow">http://blog.ubuntu-tweak.com/guide/how-to-fix-the-source-list-files</a> to understand and fix my sources file. By the time I had removed the "bad lines" from the sources.list, there were no lines left. At this point I was able to apt-get update successfully, but rvm install ruby was still failing because it now wasn't able to locate the necessary dependencies. I'm starting to consider a complete fresh install because I have no idea what else to do, but I figured I would ask for help here first.</p>
