Apply network configuration permanently

$ sudo netplan apply

$ sudo netplan generate

$ sudo netplan set ethernets.[interface].dhcp4=true

$ sudo netplan try --timeout [120]

$ sudo netplan --debug apply

$ netplan status

$ netplan get [ethernets]

netplan [--debug] command [options]

netplan is a network configuration utility for Ubuntu and other Linux distributions. It uses YAML files to describe network interfaces and generates configuration for backend renderers like NetworkManager or systemd-networkd.
The abstraction layer allows the same configuration to work with different network management backends, simplifying network setup across environments.

--debug

Enable debug output

Use alternate root directory

Timeout for try command before rollback

Configuration files are stored in **/etc/netplan/*.yaml**
Example YAML:

$ network:
  version: 2
  ethernets:
    eth0:
      dhcp4: true

apply

Apply network configuration and make persistent

Generate backend-specific configuration files

Try configuration changes with automatic rollback

Get current configuration values

Set configuration values

Display current network status

Show available features

YAML syntax errors prevent configuration from applying. The try command requires a timeout or manual confirmation. Backend must be installed (NetworkManager or systemd-networkd). Changes to configuration files require apply to take effect.

netplan was developed by Canonical for Ubuntu, first appearing in Ubuntu 17.10. It was designed to provide a unified network configuration system that works across different network backends while being human-readable.
