Software updates on the Ubuntu system will fail because Cockpit on Ubuntu doesn’t detect a network
connection. To fix this, you must use NetworkManager instead of the default networkd.
You need to be root or sudo root for all these commands. Edit your netplan file in
and add the following two lines under
version: 2 renderer: NetworkManager
Remember that spaces matter in YAML files.
You will then need install network-manager.
apt install network-manager
systemctl disable systemd-networkd
systemctl enable network-manager
Apply your new settings
