I am new to linux (I am running Ubuntu 22.04.2 LTS) and I am trying to get mujoco-py to work. I have installed mujoco200 and I am attempting to install mujoco-py-2.0.2. I am following this guide: https://www.chenshiyu.top/blog/2019/06/19/Tutorial-Installation-and-Configuration-of-MuJoCo-Gym-Baselines/. I am at part 1.2.4. In attempting to run import mujoco-py I get the following error:

On the GitHub page for mujoco-py (https://github.com/openai/mujoco-py#ubuntu-installtion-troubleshooting) it says to run: sudo apt install libosmesa6-dev libgl1-mesa-glx libglfw3 which I did. I still get the error. I attempted to run the following suggestion sudo ln -s /usr/lib/x86_64-linux-gnu/libGL.so.1 /usr/lib/x86_64-linux-gnu/libGL.so; however, I get the following error,
ln: failed to create symbolic link '/usr/lib/x86_64-linux-gnu/libGL.so': File exists
I am not sure if I am creating this symbolic link correctly. In searching my files I cannot find libGL.so or libGL.so.1. Any help you can provide would be much appreciated. Thank you.
