Comment 15 for bug 1881832

I have a comment to issue reported by user "k76". I guess you updated your netplan config file in a wrong way. It is unlikely that your network interface is "eth0" in Ubuntu 20.04. Check what is your real network interface name with cli command "ip a" or "ipconfig"...

"eth0" was in the past the first Ethernet interface. It was working good for long time and it was really boring so developers (systemd??) decided to generate new cool names that are different on each PC so users have more fun when they troubleshoot their network issues.. ;-)
