I also got an ERROR saying there is no move_base/move_base to launch. I found move_base (both the package folder AND executable) in /opt/ros/kinetic/lib/ There were also move_base folders in catkin_ws/devel/lib/ and catkin_ws/devel/share/ However, these catkin_ws move_base folders were empty or incomplete due to a bad build or an incomplete build that I had attempted initially. The problem was caused by not cleaning up a bad build in my catkin_ws directories. I deleted move_base folders from catkin_ws/devel/ lib and share, along with many other navigation related directories that should not have been there. I then could launch move_base.launch
