Public bug reported: This bug happened during the installation of Dapper.
I have to mention that on a really rare situation, the ubuntu.com servers where down while I was trying to install my system. On the right moment the installer where trying to configure the apt sources, it failed because of the servers on its downtime. Given that situation, i tried over and over again to configure the sources each time it failed, suddenly I tried to see what happened to ubuntu.com and confirmed the servers where down. THE BUG IS: I confirmed that every time I tried to configure the sources and failed, the installer porcess added some extra lines on "sources.list". Those lines where added to the file instead of overwrite it entirely or just leave it alone. That situation got me to a really messy situation when I tried to use "apt-get update" because it alerted me about the duplication of packages sources uris on "sources.list". I hope you can fix this issue, good luck on this, you are making a great distro.
