netplan fails to apply IP address

[KurtB]

Upon reboot, netplan fails to assign an IP address to a previous working device.

In this instance, `eno1` is up, but fails to assign the IP address.
The `eno2` device seems to work.

$ netplan --debug apply
...
DEBUG:eno1 not found in {}

Any ideas?

This is a red herring. The debug message does not mean that there isn't configuration.

Is it possible that the MAC address changes across reboots? Could you enable debugging on systemd-networkd; then reboot so we can see if the interfaces are available at the time netwrokd will try to apply the configuration?
