Perhaps unsupported in Ubuntu, not in Debian. I believe this to be a genuine issue in APT: systemd provided the rope, but apt used it to hang itself to a possibly stuck external daemon. Not a problem, if one knows how to work around it: please do add DPkg::Inhibit-Shutdown to the apt.conf(5) man page. A package manager should be able to operate even when the only working process in the system is init=/bin/sh. As far as I can tell other package managers avoid linking against libsystemd even in distributions that rely exclusively on systemd.
