Ubuntu/Debian Network Configuration with netplan
Netplan reads YAML files from /etc/netplan/. Use either NetworkManager or systemd-networkd as the renderer according to the image. The examples below use networkd; change it to NetworkManager if the image does not use networkd. Do not manage the same interface with both nmcli and netplan at the same time.
