The Supervisor utilizes the Network Manager on the host to offer network information to add-ons and to give you the option to manage the network interfaces using the UI or via the command-line.
This requires NetworkManager to be installed, active and in control of at least one network interface on the host.
The current minimum supported version of NetworkManager is: 1.14.6.
If you have not already, install or update Network Manager on the host.
When it is installed, you need to make sure it manages at least one interface see the documentation for the network manager.
Here are some example files that can be used to make the Network Manager control all physical interfaces.
[main] dns=default plugins=keyfile autoconnect-retries-default=0 rc-manager=file [keyfile] unmanaged-devices=type:bridge;type:tun;driver:veth [logging] backend=journal

You can also just re-run our convenience installation script.
If you haven’t done anything manually with the network on the host, you should just re-run the convenience installation script.
When you have changed your network configuration manually or with the script, you should restart the host so the change will be populated to all services that needs it.
