Looks like: https://stackoverflow.com/questions/41102299/pip-error-module-object-has-no-attribute-cryptography-has-ssl-st

$ dpkg -l '*python-openssl*'
ii  python-openssl                                                0.15.1-2ubuntu0.2   

$ pip freeze|grep pyOpenSSL
pyOpenSSL==19.0.0

apt-get --auto-remove remove python-openssl

solved the problem
