Indeed I did install octave using flatpak. Setting the environment variable to python 3 did the trick.

setenv PYTHON python3
sympref reset

Thank you for the prompt and helpful responses.

Is there a reason you have set PYTHON in your environment to be
specifically "python3.6"? Instead of, say "python3"? Did you have that
set previously, or did you find that advice somewhere?

Yeah, Octave's "path" is not the same as the shell PATH. That's not the
problem here.

I am going to guess that you have installed Octave with Flatpak or Snap,
is that right?

If so, Octave does not have access to the /usr filesystem that is part
of your operating system, it is confined to its own /usr. You probably
want to try setting PYTHON to be "python3" instead of "python3.6".
