This is where the problem resides - - - - note the "${debian_codename}" in
both line 2 and 13 - - - I am working on a devuan
(daedalus) system and this is one area where I haven't been able to get the
system to use what is automagically correct.
The Postgresql apt repository has NO mention of anything Devuan only Debian
and Ubuntu.

The problem is that keyrings have been deprecated.
Instead one is to use trusted.gpg.d which is different.
I have not been able to find a way to add the whatevers to
/etc/apt/trusted.gpg.d which is where things are supposed to be placed now.
(Noticed that you are using keyserver.ubuntu - - - you did notice that I
was doing this on a Devuan system - - - yes?)

So - - - I have not been able to solve my apt issues - - - please?
