Bug#1086726: [debian-mysql] Bug#1086726: galera-arbitrator-4: preinst script creating _galera user should belong to galera-arbitrator-4 instead of galera-4

[Otto Kekäläinen]

Hi!

I merged your submission. Thanks!

I also fixed the CI so that it can run again, and it uncovered a
regression: https://salsa.debian.org/mariadb-team/galera-4/-/jobs/6581726

    /var/lib/dpkg/tmp.ci/preinst: line 12: adduser: command not found

Do you want to take a look and do a follow-up submission?

Thanks
