The update-alternatives command should create the
/etc/alternatives/python link for you just fine.

Sorry, had to dogsit for a bit.
env is in usr/bin, don't know how I missed it before.
There are a few pythons in usr/bin (2 (link to py2.7), 2.7 (shared
lib), 3 (link to py3.8), 3.8 (exe), and a few more py 3) but none in
alternatives.
Setting usr/bin/python to point to /etc/alternatives/python won't work
if it's not there.
Do I have to set the python path environment variable? I'm only
guessing but is 'env' a list of environment variables? All I know is
that it's a library.

Take a look at what python stuff is in /usr/bin right now. There
should be several symbolic links.
* ls -l /usr/bin/python* /etc/alternatives/python*
My guess is that /usr/bin/python is either missing altogether or
is pointing to some version of python2 that has been removed. If
you run this command it will set /usr/bin/python to point to
/etc/alternatives/python, which in turn will point to
/usr/bin/python3.
* sudo update-alternatives --install /usr/bin/python python
/usr/bin/python3 1
* python --version
should now return 'Python 3.8.2'
That should get the 'python' command pointing to a valid python
installation again. Your next issue might be that some older
python scripts will have to be updated to be compatible with
python3, but fixing those will be a one-time thing and will get
you positioned well for the long term.

I think it's Gimp python as this has been an issue before, as I
mentioned, but I don't know what specifically to install, it
doesn't seem to be 'Gimp python' as it was before.
I've tinkered with thonny for writing python scripts for Gimp and
it that it was pygimp but I'm stumped. I don't want to randomly
install stuff in case I make it worse.

Here are the steps I used:
1. Check current system python version is 2.x
sudo python --version
2. Execute this command to switch to python3
sudo update-alternatives --install /usr/bin/python
python /usr/bin/python3 1
3. Verify system python version is now 3.x
sudo python --version
based on steps I found in this post:

I'm surprised that python (for Gimp) isn't installed by
default on Linux, that's what's caused this issue before.
I'll try anything to get it working, python plays a large
part of my Gimp workflow.
Sorry to ask but how would I manually set python3 as the
default?

Can you try 'python3'? On a side note, I was surprised
that python3 was note the default in the upgrade. I had
manually set python3 as the default in my 19.10 and that
was switched back to python 2.x when I upgraded.

So I did a clean install and Gimp now loads and works
mostly OK. The issue now is it can't find python.
I know this has been an issue with Gimp on Linux
previously and it could be solved by 'sudo apt install
gimp-python', but this doesn't work.
Output from terminal '/usr/bin/env: ‘python’: No such
file or directory'
I can see there's no env in bin.
Does anyone know how to fix this please?
I have searched online but the solutions aren't
relevant to the current Gimp version/Linux.
