[PLUG] github connection issue, part 2

[Rich Shepard]

Yesterday I resolved the missing github private ssh key; I'm able to push
changes from my local web site repo to the github repo using ``git push
origin'' and entering my github pass phrase. That's the first half of my
problem resolved.

The second half, which makes no sense to me or Paul Mullen who developed the
site, is that I still cannot rebuild the site after making changes to the
content. The Makefile which up until 2 weeks ago worked flawlessly now
fails:

$ make zero-to-prod 
[ -d /home/rshepard/development/web-site/aes-2023/public ] && rm -fr /home/rshepard/development/web-site/aes-2023/public

make: [clean] Error 1 (ignored)

There is a ``clean'' section in the Makefile and that's ignored. But, why
hugo (the site framework) and go (Hugo's language) cannot connect to github
is the problem. Is the problem with a Certificate Authority at github's end?
Hugho's end? Go's end? It apparently isn't at my end.

All help appreciated,

Rich
