Thank you for your response, I went through the link you mentioned and had the following issues:
I had already setup the environment source from the video I mentioned earlier with the line:
source opt/ros/dashing/setup.bash
Is there a way to change it, or would it require a clean install?
Moreover, as I am new to this, I am having some trouble understanding the "MPA - to - Ros2" steps mentioned in the document. Can you please elaborate on the command lines I should execute for the steps mentioned. Thanks again!
