add the workspace to your ROS permission denied

edit

hello I have a problem to add the workspace in the ROS environment.

I am following the tutorial and when I have to add the workspace in the ROS environment

$ . ~/catkin_ws/devel/setup.bash

I get the following:

bash: /home/jonatan/catkin_ws/devel/setup.bash: permission denied

What should I do to solve it?
