Using ubuntu-20.04-live-server-amd64.iso I created an USB and did fresh
install, after fresh install I ran apt get update followed by apt get
upgrade, I then removed the existing yaml in /etc/netplan and added
99_config.yaml:
labuser@lab:~$ sudo nano /etc/netplan/99_config.yaml
labuser@lab:~$ sudo cat /etc/netplan/99_config.yaml
