For your system, it should have this line: deb http://code.ros.org/packages/ros/ubuntu lucid main I would guess that you have 'maverick' in there, instead of 'lucid,' which will make apt-get pull debs for the wrong Ubuntu version. Assuming that that's problem, fix the line, 'sudo apt-get update' and try again. brian.
