My Ubuntu client says that the wired connection is unmanaged

Question

This is what is showing when I look at the wired management. I don't know what I did that it's showing all of these and I can no longer access the internet.

Answer 1

These two steps should make the wired connection managed, as found in this answer

sudo touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf
sudo systemctl restart NetworkManager
