Now that the system is fully upgraded, does systemd still fail to boot
and drop you into emergency mode?
In that case, please add systemd.log_level=debug to the kernel command
line and attach the output of "journalctl -alb"

Ok, so this sounds like this is specific to systemd emergency mode.
Assuming systemd boots properly for you now, it would be interesting to
know, if dpkg now works properly as well when booted into a regular mode.

That somehow sounds like something with your dbus installation is broken.
What is the output of
$ ls -al /usr/lib/dbus-1.0/dbus-daemon-launch-helper

Is the dbus package installed? What's the output of "systemctl status
dbus.socket dbus.service"?
You might consider attaching the full output of the systemd state via
"systemd-analyze dump"
