22.04 netplan apply fails

[diegomontoya2]

Clean install of 22.04 server edition and any changes triggered by netplan will fail. This is a rather serious bug and not sure if 22.04 no longer supports netplan runtime changes or is this a regression somewhere?

1. 00-installer-config.yaml

# This is the network config written by 'subiquity'
network:
  ethernets:
    eno1:
      dhcp4: true
    enp4s0:
      dhcp4: true
  version: 2

2. netplan apply

netplan --debug generate is green so the yaml is perfect
