Create a file in /etc/netplan:
sudo -H gedit /etc/netplan/networkmanager.yaml
or
sudo pico /etc/netplan/networkmanager.yaml
Place this content in that file, keeping the exact same indentation, spacing, and no tabs:
network:
version: 2
renderer: NetworkManager
Then, in terminal
:
sudo netplan generate
sudo netplan apply
reboot
Then use the NetworkManager GUI tools to configure your “Wired Connection”.
