Hi, I am trying to run the following command from MoveIt Tutorial

roslaunch moveit_servo spacenav_cpp.launch

However , getting the following error

Could not open the space navigator device. Did you remember to run spacenavd (as root)?
I tried resolving it using the following link , however still getting the following issue

sudo bash
root@akumar-ThinkPad-P17-Gen-2i:/home/akumar/ws_moveit/src/joystick_drivers/spacenav_node# rosrun spacenav spacenavd

Command 'rosrun' not found, but can be installed with:

apt install rosbash

root@akumar-ThinkPad-P17-Gen-2i:/home/akumar/ws_moveit/src/joystick_drivers/spacenav_node# apt install rosbash
