Hi,

This message means that the user account does not have permission to write to that location. You can check permissions by navigating to the preceding folder (/usr/local/ in this case) and running the command "ls -la" to check ownership and permissions.

Use chmod command to fix the permissions and allow your user account to write to the location.

sudo chmod u+rwx -R /path/to/directory

will give your user account read, write, and execute permissions, and will allow any other account to read or execute (run) files in the directory or subdirectories.

Sorry, i have this problem when i am trying to build a simulink model for ROS2 real-time implementation with Colcon. I gave all the permissions but the problem is still here. Maybe any suggestions?
