Yes indeed!

I tried the example as seen in “4.3.2 Substitute Server Authorization”:

$ guix build emacs --dry-run
substitute: updating list of substitutes from 'https://mirror.hydra.gnu.org'...  18.6%guix substitute: error: TLS error in procedure 'read_from_session_record_port': The TLS connection was non-properly terminated.
guix build: error: substituter `substitute' died unexpectedly

So apparently, guix is using the obsolete hydra server.

This file shows only one key, but that one is listed four times as like:

Well, I am not sure how to proceed with my old version of guix.

I wonder if the listed key is as well valid for https://ci.guix.gnu.org
just the same as it used to be valid for https://mirror.hydra.gnu.org.

If not, where can I get the new, correct one?

Once I have the keyfile, I am supposed to continue with section
 “4.3.2 Substitute Server Authorization”,
right?

Then I would try:
 # guix-daemon --substitute-urls=https://ci.guix.gnu.org
 # guix archive --authorize < my/path/to/ci.guix.gnu.org.pub

Is that correct?

Would that remove the obsolete substitute server information in the
same go?

best regards
Kai
