Looking up at this outside FAI context, I did a few rounds of
debootstrap buster.  I hit a similar issue as yours at first,
and ended up needing to force specifiying dbus-user-session as
provider of dbus-session-bus to allow lightdm to install:

	sudo debootstrap buster chroot-buster/ \
		--include=dbus-user-session,lightdm

Otherwise I was seeing this at the end of debootstrap output:

	W: Failure while configuring base packages.  This will be re-attempted up to five times.
	W: See /tmp/chroot-buster/debootstrap/debootstrap.log for details (possibly the package dconf-service is at fault)

and that as first instance of "dpkg: error" in the debootstrap
log:

	dpkg: dependency problems prevent configuration of dconf-service:
	 dconf-service depends on default-dbus-session-bus | dbus-session-bus; however:
	  Package default-dbus-session-bus is not installed.
	  Package dbus-session-bus is not installed.
	
	dpkg: error processing package dconf-service (--configure):
	 dependency problems - leaving unconfigured

Not sure why the installation of lightdm is not seamless though.
This is reproducible either with debootstrap or apt on my side.

Kind Regards,
