However, Bill said that the support for windows via Docker is intended
primarily for introductory classes using mesa.

I used this same WSL to install an run mesa (version 6794, sdk version
20141212) in 2017 though, using the same commands as I have done now. It
installed smoothly then. However, just now I tried to install it again (the
older version) and the same set of error messages came up. For now, I think
I will install the Mesa docker and learn the basics until I get a Linux OS
installed.

Thank you everyone for your valuable time and advise on the problem.

Yours faithfully,
