When I start the exercise on xacro the top of the terminal reads this:
/opt/ros/kinetic/setup.bash: No such file or directory
I think I heard all of them have been switch to noetic and I can source the noeitc envirnoment. However, it does not recognize my ros packages and most of the ros commands don’t seem to work. I can switch back to the previous URDF lesson and they work fine. I get this message when I run the roscd to my packages:
Hi,
Sorry for the inconvenience, we were updating the system to noetic and we missed to indicate that.
To fix this for the moment do the following everytime you open UNIT 4 and Unit5:
cd ~/catkin_ws/
rm -rf build devel
source /home/simulations/public_sim_ws/devel/setup.bash
catkin_make
source devel/setup.bash
rospack profile
And in each terminal always source the workspace:
cd ~/catkin_ws/
source devel/setup.bash
rospack profile
Sorry again for the inconvenience and hope this helps
