Comment 2 for bug 1931178

From my several brief tests, this does not appear to be a (recent) regression.

I do see in the apt-key manpage that apt-key is deprecated as of Focal and will be removed after Debian 11 / Ubuntu J/22.04. In the meantime, the `cp some-repo-key.gpg /etc/apt/trusted.gpg.d` method has been brought to the customer as a "workaround" / the new correct method.

The signed-by option is a good idea, too!

Thank you for your response letting us know that a change to apt-key will be skipped.
