Comment 5 for bug 1930121

This bug can also be triggered if the user has a virtual python env active. The post install script uses the python version from the callers environment instead of the system version for which ubuntu-advantage-tools was installed. I think it would be safe to hardcode the python bin path in the post install script since it is built for that version only.

# python -m venv test
# . test/bin/activate
(test) # apt install --force-reinstall=true ubuntu-advantage-tools
