Netplan Configuration

One file does it all.

$ sudo nano /etc/netplan/01-network-manager-all.yaml

Network Manager

For Desktops. The default install looks as below.

network:
version: 2
renderer: NetworkManager

networkd

For headless servers without wifi, everything by the command line.

network:
version: 2
renderer: networkd

netplan generate

Generate the files without applying them. Great for checking syntax.

$ sudo netplan generate

netplan try

Apply the latest modifications with a timed revert to reverse changes. Try before you buy.

$ sudo netplan try

netplan apply

Apply the latest changes without concern for reverting the files back to their former selves.

$ sudo netplan --debug apply

netplan get

Retrieve and display the current configuration files.

$ sudo netplan get
