Job for lightdm.service failed because the control process exited with error code. See "systemctl status lightdm.service" and "journalctl -xe" for details.
invoke-rc.d: initscript lightdm, action "start" failed.
dpkg: error processing package lightdm (--configure):
subprocess installed post-installation script returned error exit status 1
This is reproducible in a cloud instance/VM (or a server install, etc) with
sudo apt-get install lightdm --no-install-
$ sudo lightdm -d

So apparently something in 1.19 changed the handling of seats and now fails if there is no seat. That makes automated testing much harder as we don't have seats in these environments.

Installation works with recommends, but that pulls in 560(!) packages/800 MB, and I'd rather avoid adding this extra weight on every test run.
