You can build a default file following the procedure:

1. Move older file

   sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak

2. Then open software-properties-gtk to build a new one. Type the below command in a terminal

   software-properties-gtk

In the window

Select all four catagory in Ubuntu Software tab

Select precise-security, precise-updates and precise-backports catagory in Updates tab.

Select Canonical partner and Intependent catagory from Other software tab.

That's it. Now you will have a new deafault error free sources.list file.
