Hi everyone,

when starting my project with roslaunch i get the following error. :

File "/opt/ros/melodic/lib/python2.7/dist-packages/roslaunch/loader.py", line 536, in paramvalue p = subprocess.Popen(command, stdout=subprocess.PIPE) File "/usr/lib/python2.7/subprocess.py", line 394, in _init__ errread, errwrite) File "/usr/lib/python2.7/subprocess.py", line 1047, in executechild raise child_exception OSError: [Errno 13] Permission denied

Unfortunately, this is my first time working with ros and ubuntu and I have to do this for my university project.

What information do you need to make the problem more precise?
