Public bug reported:
As of commit[0] setuptools appear to be incompatible with Python3.5 as
shipped by xenial.
This makes a virtualenv for Python3 fail with a syntax error:
# virtualenv -ppython3 venv
Already using interpreter /usr/bin/python3
Using base prefix '/usr'
New python executable in /root/venv/bin/python3
Also creating executable in /root/venv/bin/python
Installing setuptools, pkg_resources, pip, wheel...done.
# venv/bin/pip install pyyaml
DEPRECATION: Python 3.5 reached the end of its life on September 13th, 2020.
Please upgrade your Python as Python 3.5 is no longer maintained. pip 21.0 will
drop support for Python 3.5 in January 2021. pip 21.0 will remove supp
ort for this functionality.

As Python3.5 is EOL we might need to pin setuptools for virtualenv to a
lower version
