System:

• Ubuntu 20.04
• ROS2 Foxy
• setuptools 68.0.0

I recently installed ROS2 Foxy on my computer. The installation finished successfully and tested ROS by running the talker demo and it worked fine. However, when I tried compiling a new package that I created with the example publisher from the documentation, I get a compilation error "no module name sphinx.setup_command". I installed sphinx by running sudo apt-get install python3-sphinx and I am still getting this error. I assume the issue related to setuptools. Any idea why I am getting this error ?

I couldn't upload a picture so I copied the output.
