Dear Maintainer,
Package galera-arbitrator-4 provides a standalone daemon which doesn't
depend on the plugin library provided by package galera-4: typically the
arbitrator runs on a separate system so one installs galera-arbitrator-4
without also installing mariadb so without also installing galera-4.
Installing galera-arbitrator-4 without having ever installed galera-4
leads to this error:
# systemctl status garb

Creating the missing user _galera fixed the Debian-related issue after
restarting garb.service (garbd requires other settings anyways that
aren't Debian-related). I would have expected the user to be created
automatically by an install script.
Actually this script does exist in the debian package (commit a42ecdf9) but was
added for the package galera-4 where it's not useful (the
plugin library typically runs as part of mariadb with the mysql user).
Renaming the preinst file solves the issue:
diff --git a/debian/galera-4.preinst b/debian/galera-arbitrator-4.preinst
similarity index 100%
rename from debian/galera-4.preinst
rename to debian/galera-arbitrator-4.preinst
Now after a first installation it only fails as expected because it's
not configured:
Nov 04 19:56:22 trixie-amd64 garb-systemd[23745]: ERROR! List of GALERA_NODES
is not configured
