Looks like an installation problem. On Ubuntu 20.04, python3-pip depends on python3-wheel:
$ apt-cache show python3-pip | grep Depends Depends: ca-certificates, python3-distutils, python3-setuptools, python3-wheel, python-pip-whl (= 20.0.2-5ubuntu1), python3:any And it gets pulled during an installation attempt: $ apt install python3-pip Reading package lists...
