Anover advice:
1. Avoid unsupported versions of software (Ubuntu-16.04 has only payed 
support for more than a year) and localize its usage if there is no 
other way.

2. Use venv (virtualenv for Python-2.7) to keep packages installed by 
pip isolated from system .deb's.

Ubuntu-20.04 has (already unsupported) Python-2.7 in addition to 3.8 and 
3.9.

It is better to keep primary system up to date and to use containers 
(LXC, docker, etc.) or fully virtualized systems for special needs.
