Installing Django for Ubuntu

I'm going through the tutorial to install Django for Ubunto 20.04 LTS but when I get to the section to verify my install with:

django-admin --version

I get the following error:

Traceback (most recent call last):
File "/usr/bin/django-admin", line 2, in <module>
from django.core import management
ModuleNotFoundError: No module named 'django'

Does anyone know what the fix for this is?

 

Did the previous steps in the installation go OK with not errors?
I would instead of

Code:

update-alternatives --install /usr/bin/python python /usr/bin/python3 1

do

Code:

apt install python-is-python3

in case there is more involved than the symlink.
