Hi Malcolm,

if you trust me to produce BIND 9 code directly from the upstream,
I guess that trust can be transitioned to the packaging repositories.

The packaging is created in a way that makes it easy to create
packages for both Ubuntu and Debian in the same way.

I'll add some text to the KB, thanks for raising the issue here.

P.S.: However, you are right that for Ubuntu PPAs there could be just
a dummy package with no keys and that would make it little less
confusing. The package is setup like this intentionally for now
and it will get gradually upgraded to the signed-by method as the
distributions supporting that will get deprecated. As of now, the
change you mentioned will be included in Debian Trixie that hasn't
been released yet, and there's too many installations that still use
the old method
