@ddstreet I have rebooted both a VM and the original machine without my work around of the macaddress option in the bridge configuration and they are both now working on the reboot.
I can see from the apt/history.log that between first reporting this issue and now, the systemd:amd64 package was updated: Start-Date: 2020-05-27 17:36:34 Commandline: apt-get dist-upgrade Requested-By: user (1000) Upgrade: libsystemd0:amd64 (245.4-4ubuntu3, 245.4-4ubuntu3.1), ubuntu-standard:amd64 (1.450, 1.450.1), udev:amd64 (245.4-4ubuntu3, 245.4-4ubuntu3.1), ubuntu-server:amd64 (1.450, 1.450.1), libnss-mymachines:amd64 (245.4-4ubuntu3, 245.4-4ubuntu3.1), libudev1:amd64 (245.4-4ubuntu3, 245.4-4ubuntu3.1), systemd-timesyncd:amd64 (245.4-4ubuntu3, 245.4-4ubuntu3.1), ubuntu-minimal:amd64 (1.450, 1.450.1), systemd-sysv:amd64 (245.4-4ubuntu3, 245.4-4ubuntu3.1), libpam-systemd:amd64 (245.4-4ubuntu3, 245.4-4ubuntu3.1), systemd:amd64 (245.4-4ubuntu3, 245.4-4ubuntu3.1), libnss-systemd:amd64 (245.4-4ubuntu3, 245.4-4ubuntu3.1), systemd-container:amd64 (245.4-4ubuntu3, 245.4-4ubuntu3.1) End-Date: 2020-05-27 17:37:03 So for me this issue has now been resolved.
