OK, I found a workaround:
$ sudo apt install systemd=229-4ubuntu4 libsystemd0=229-4ubuntu4
libpam-systemd=229-4ubuntu4
Looks like it's not a coreutils nor a who issue, it's a systemd issue,
perhaps related to backport, since I'm not seeing it on bionic.
Of course next upgrade will break it again, until the packages are
fixed.
