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:<br />version: 2<br />renderer: NetworkManager
Check the file permissions and then, in terminal:
sudo netplan generate<br />sudo netplan apply<br />reboot
Then use the NetworkManager GUI tools to configure your “Wired Connection”.
