Comment 14 for bug 1881832

I have an update. I tried yesterday TrueNAS Core 12.0U1.1 and I tried to install Ubuntu server 20.04.1 to test Virtual machine configuration. I cannot report any good news, bug was not fixed. Installation of Ubuntu was easy, it got IPv4 address from local DHCP server and installed several updates during installation process. Once installation was finished and virtual machine was rebooted, new virtual server was not able to get IP address from DHCP server. I have to manually fix file /etc/netplan/00-installer-config.yaml, network interface was wrong (by 1).

This issue is really simple to reproduce. Ubuntu and TruNAS Core are free software, anyone can download these and replicate the issue.... I believe there is a bug in Ubuntu installer, it creates netplan config file in a wrong way. I am not sure just now but I think I modified enp0s5 to enp0s4. Virtual machine had the only one virtual network interface and I use VirtIO network adapter.
