There is a cfg file /etc/cloud/cloud.cfg.d/subiquity-disable-cloudinit-networking.cfg which disables cloud-init to configure network.

The content of this file is
    network: {config: disabled}

With this file exists, cloud-init will skip network configuration, this is as cloud-init designed.

Not sure why ubuntu20.04 Live Server added this cfg ?
