Installing the file using (package-install-file
"gnu-elpa-keyring-update-pkg.el")
does create the elpa directory with the  .el fles and byte-compiles it but
it does
not place the etc sub-directory and does not create the
gnu-elpa-keyring-update-2022.12.1.signed file in the elpa directory.
- To handle the etc directory, I just copied it
- As far as the missing gnu-elpa-keyring-update-2022.12.1.signed file I
tried without it
  and then tried with a copy of that file.

The problem with gnu elpa was solved.  However I still had a http 404
problem if nongnu,
 ("nongnu" . "https://elpa.nongnu.org/nongnu") ,
was included inside the the `package-archives`:
  with  `M-x package-list-packages`

error in process filter: Error retrieving:
https://elpa.nongnu.org/nongnuarchive-contents (error http 404)

The *problem was the missing trailing slash in the URL string*!

The problem was inside my init.el file.

Would it make sense to include a function that would add cons cells in
package-archives and would check for missing trailing slash?
That function could also deal with various issues that occurred over time
like the one for emacs 26.1 and 26.2 having to set
gnutls-algorithm-priority?

Thanks Stephan & Micha!
