Not a tragic issue since it looks that postinst script proceeds anyway with the 
rest
of the configuration, but if you look at snippets from debhelper 
deb-systemd-invoke is always
called only if systemd is PID1. The patch at the bottom should fix the issue.

Thanks for the patch!

On the other hand the dh_installsystemd command adds the following code block below to the postinst script. I'm missing here the "deb-systemd-invoke restart" command here, but I'm not sure if it is really needed. I tend to remove completely our hand written code and leave the job to debhelper. if [ "$1" = "configure" ] || [ "$1" = "abort-upgrade" ] || [ "$1" = "abort-deconfigure" ] || [ "$1" = "abort-remove" ] ; then # This will only remove masks created by d-s-h on package removal. deb-systemd-helper unmask 'proftpd.service' >/dev/null || true if deb-systemd-helper --quiet was-enabled 'proftpd.service'; then deb-systemd-helper enable 'proftpd.service' >/dev/null || true # Update the statefile to add new symlinks (if any), which need to be cleaned deb-systemd-helper update-state 'proftpd.service' >/dev/null || true
