Comment 1 for bug 2004131

> resolv_conf:

You don't want to use that module on Ubuntu 22.04. Note the distro list[1] doesn't contain Ubuntu as a supported distro.

> network:

Do I understand correctly that you put this network config in user.vendor-data?

Lxd uses a different key for network, see cloud-init.network-config in lxd's docs [2]. This should be better documented in cloud-init, which doesn't document network configuration of this datasource at all.
