Package: cacti (Filing against cacti for now for visibility, actual root cause might be elsewhere.)
After uploading mariadb 1:10.11.1-4 the autopkgtests for cacti started failing on all architectures. I suspect the problem is that the mariadbd server is not running at the time when dbconfig-common attempts to create credentials for cacti. Note in log https://ci.debian.net/data/autopkgtest/testing/s390x/d/dbconfig-common/31204959/log.gz section: Setting up mariadb-server (1:10.11.1-4) ...

Line 145 in /usr/bin/deb-systemd-invoke is: system('systemctl', '--quiet', @instance_args, $action, @start_units) == 0 or die("Could not execute systemctl: $!"); Looking at previous log https://ci.debian.net/data/autopkgtest/testing/amd64/c/cacti/31113621/log.gz (with MariaDB 1:10.11.1-3) this section has: Setting up mariadb-server (1:10.11.1-3) ... Created symlink /etc/systemd/system/multi-user.target.wants/mariadb.service → /lib/systemd/system/mariadb.service. There is nothing about deb-systemd-invoke. When I run this manually inside failed cacti autopkgtest shell I get: root@fb9c1752c1c7:/tmp/autopkgtest.n2vt3p/build.b5I/real-tree# /usr/bin/deb-systemd-invoke restart mariadb sh: 1: systemctl: not found Can't exec "systemctl": No such file or directory at /usr/bin/deb-systemd-invoke line 133. mariadb is a disabled or a static unit not running, not starting it.

After applying some debugging seems the script attempts to run: systemctl --quiet --system restart mariadb Checking what the systemd service file tries to run: # grep ExecStartPre /lib/systemd/system/mariadb.service ExecStartPre=/usr/bin/install -m 755 -o mysql -g root -d /var/run/mysqld ExecStartPre=/bin/sh -c "systemctl unset-environment _WSREP_START_POSITION" ExecStartPre=/bin/sh -c "[ ! -e /usr/bin/galera_recovery ] && VAR= || \ If systemctl is used from package 'systemctl' (not real, but systemd shim) the start is bound to fail: # systemctl unset-environment ERROR:systemctl:Unknown operation unset-environment.

Probably not, the same version of cacti has been in Debian for a long time. Latest upload of dbconfig-common was on Feb 2nd, and after that MariaDB 10.11.1-3 was still working on Feb 3rd.. Suggestions on what to debug next welcome.
