Comment 60 for bug 1770082

Just tried with a fresh installed Ubuntu SERVER 18.04.1.
The interface now got renamed but IP address is not applied, both static and DHCP.

If I run "netplan apply" just after reboot+login, network interface is configured correctly (again, both with static/DHCP address).

I'm going to remove all of this netplan stuff and get back to old working /ets/network/interface...
