> This backport to 18.04 LTS broke all our OpenStack compute nodes I've opened bug 1937117 to revert this fix, however keep in mind your networkd configuration is incorrect and should be fixed as you will have problems later if you continue to mix systemd-networkd management of interface(s) as well as manual/external configuration of those same systemd-networkd-managed interface(s).
