About NetworkManager

NetworkManager is a system network service that manages your network devices and connections, attempts to keep network connectivity active when available. It manages Ethernet, WiFi, mobile broadband (WWAN) and PPPoE devices while also providing VPN integration with a variety of different VPN serivces.

By default network management on Ubuntu Core is handled by systemd's networkd and netplan. While NetworkManager has some support to handle netplan configuration files, Ethernet support is disabled by default and has to be turned on explicitly to avoid conflicts with existing network configuration.
