Thanks, Dr. Mitchell, I figured it out last night—it was a silly mistake on my side.
When I installed the OS, the python command wasn’t available because I had set it up as python3 (out of habit, since I use that often). In case anyone else runs into this, installing *python-is-python3 (sudo apt install python-is-python3)* fixes the issue. Thanks a lot for your help!
