To be fait, Oliver G said "wipe out /etc/netplan", but he then cat-ed
a file inside that directory. So misunderstanding that "/etc/netplan"
is a file is rather weird.

Your initial yaml was created by cloud-init. And, IIRC, if you hadn't
removed cloud-init, it would've been recreated.

BTW, the config generated by netplan'll be in
"/run/NetworkManager/system-connections" if you're using
NetworkManager and in "/run/systemd/network" if you're using networkd.
