Please add the content of your Sources.list file . –  Uri Herrera Jul 29 '12 at 5:34

Once we look at your sources.list file, and determine what need to happen, you can either edit the line or delete it. To do that, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below.

gksudo gedit /etc/apt/sources.list

Go down to line 57, and modify it, or just delete it. Then do

sudo apt-get update

If the file is corrupt, then you can use Ubuntu Sources List Generator to create a new file.

This line might be quite important (just corrupted or with a syntax error inadvertantly introduced). Just deleting lines in /etc/apt/sources.list without knowing what they say is not good advice; you could end up preventing software from getting important updates. It really is necessary to see the file (or at least that line) to provide a solution. –  Eliah Kagan Aug 2 '12 at 1:43
@EliahKagan I understand, but since the OP hasn't supplied that info, and by looking at multiple sources.list contents, I felt that deleting that line would help. Any way I have modified the answer:) –  Mitch Aug 2 '12 at 2:04
