Solution

The solution (for now) is to avoid this version... use the following:

systemctl stop systemd-networkd
ifconfig up eno1
dhclient eno1

dpkg -i libsystemd0_237-3ubuntu10.32_amd64.deb systemd_237-3ubuntu10.32_amd64.deb
#apt install "systemd=237-3ubuntu10.32" "libsystemd0=237-3ubuntu10.32"
apt-mark hold libsystemd0=237-3ubuntu10.32 systemd=237-3ubuntu10.32

It's likely that these older package versions are no longer available via APT... They can be found here:
