I am attempting to install Indigo on a Raspberry Pi following this tutorial (http://wiki.ros.org/action/login/ROSberryPi/Installing%20ROS%20Indigo%20on%20Raspberry%20Pi)

While attempting to build console-bridge (Eg: sudo apt-get build-deep console-bridge)

I am getting the following error "E: You must put some 'source' URIs in your sources.list

I am unsure how to resolve this issue, any help would be appreciated!
