Thank you for the information. I'm still not sure of what could be wrong, the networkd files are being generated, their permissions are correct...
When you say that the configuration is not applied, do you mean that absolutely nothing is applied? Please, check the systemd journal with: journalctl -u systemd-networkd Do you see any errors emitted by networkd in the journal logs? If possible, could you attach these logs here? If you have the chance to replicate the experiment with the newest netplan.io, please also paste here the output of "networkctl list".
