ERROR: cannot launch node of type [twist_mux/twist_mux]: twist_mux
I am using Ubuntu 20.04 with ROS noetic, and when I run a progrm, it drops the error
ERROR: cannot launch node of type [twist_mux/twist_mux]: twist_mux
However, I followed the installation guide in http://wiki.ros.org/teleop_twist_keyb... and not able to solve the issue.
Looking for help on this, thanks in advance!
