I was only used to epa-file method, if I set epg-program (see the
first post for the content) it does not change the behavior.
As sources on this differ, what is the recommended way to do
gpg2.1 encryption with Gnus? what's the minimum to have in your
.gnus.el?

yes, with `/home/niasterisk/.guix-profile/bin/gpg-agent --sh
--daemon --write-env-file /home/niasterisk/.cache/gpg-agent-info

killing the agent, restarting Gnus and sending this

But gpg-agent does not continue to run or does not restart with
Gnus.
