Install Kivy on Ubuntu 18.04. not working

[Ubuntu Somethis]

I'm trying to install Kivy, a Python Framework, but run into problems using pip.

Following the instructions on https://kivy.org/doc/stable/installation/installation-linux.html I get the following error.

Can someone help? What Input should I post here to resolve the issue?

$ python -m pip install --upgrade --user pip setuptools virtualenv

---> results in

Its a Python install issue (or pip?), not a Kivy issue.  Perhaps libssl-dev was not installed when Python was installed?

Typically that would mean installing the lib, and rebuilding Python. But there may be other better solutions.

Google

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

Lots of hits :)  , and lots different solutions   :(    Pick one you like.

Before you jump in the deep end, I'd try the simple stuff like running pip3 directly from the prompt, and updating it alone. If that works then try the other packages.
