Comment by po1 for There has been a recent change in the rosdistro system, and tools such as rosdep have been updated. I would recommend the following two things:Make sure rosdep is up to date:sudo apt-get updatesudo apt-get install python-rosdepRun sudo rosdep init to reinitialize your /etc/ros/rosdep/sources.list.d, then rosdep update to update your local cache

Raspbian is debian wheezy, and the packages in the repo described in http://www.ros.org/wiki/groovy/Installation/Raspbian are made for debian wheezy (Raspbian). However, the python-* packages might be slightly out of date. As they are only python files, it should be safe to take the official ones.
