Public bug reported:
netplan can't start the 2nd NIC on a server/gateway. The definitions
are correct, the IP addresses and netmasks are correct. This server is
to replace another physical server with an identical configuration.
Thanks in advance.
Expected result

eno1: inet = 50.211.203.178
enp1s0: inet = 192.168.0.138

The correct configuration for enp1s0 should be: inet 192.168.0.138. I
tried configuring it with and without defining a gateway and routes for
the internal network; the IP address is never registered. The netplan
config, debugging information, hardware list, etc. follow.
