No luck with a solution on > ros-answers: http://answers.ros.org/question/2580/broken-packages-installing-electric-full-on-natty The technique for solving this problem goes like this: pick the first thing it says won't be installed. Try to install just that package. If the problem re-occurs, recurse. Do this until you get to a package that provides a specific reason why it won't install, and then fix that problem. Iterate. Why apt doesn't provide better error-reporting in this case is beyond me. --M -- Julian "Mac" Mason      mac@cs.duke.edu      www.cs.duke.edu/~mac
