Ubuntu - Networking - Change netplan renderer from networkd to NetworkManager

Netplan is a utility for easily configuring networking on a Linux-based system.

It supports both networkd and NetworkManager.

networkd is part of Systemd. In other word systemd-networkd used to manage network connections using Systemd.
NetworkManager is a GUI tool for configuring networking options.

Make a backup

Backup the current netplan config file:

cp /etc/netplan/01-netcfg.yaml /backup/netplan/

Change the Renderer to NetworkManager

Edit /etc/netplan/01-network-manager-all.yaml:

/etc/netplan/01-network-manager-all.yaml

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  #renderer: networkd
  renderer: NetworkManager  
  ethernets:
    enp3s0:
      dhcp4: yes

NOTE: Notice that networkd is commented out with the hash in front.

Also notice that the renderer is set to NetworkManager.
