Oh no, I can't read (and neither can Jeffrey ;-)

The correct URL for cloning over SSH starts git at github (i.e. git is
the username, not the git:// protocol).

Jeffrey's second URL starts with git:// which is no longer supported,
as explained at
https://github.blog/2021-09-01-improving-git-protocol-security-github/

Switching to use the git at github.com URL should work.

I still don't know why he couldn't use the unauthenticated HTTPS URL,
because that works fine for me on gcc112 with /usr/bin/git or the
newer on in /opt/cfarm.
