Cockpit Unmanage Interfaces

When you installed Cockpit in Debian system and some of your interfaces are showing under the Unmanage interfaces section, the solution is to comment out the intefaces in /etc/network/interfaces. This will make the network-manager manage the interfaces; therefore, Cockpit will be able to manage the interfaces.

root@debian:~# nmcli device status
DEVICE  TYPE      STATE      CONNECTION 
ens18   ethernet  unmanaged  --         
lo      loopback  unmanaged  --  

Comment out the physical interfaces in /etc/network/interfaces.

sed -i 's/allow/#allow/g' /etc/network/interfaces
sed -i 's/iface ens18/#iface ens18/g' /etc/network/interfaces

Restart the network-manager

systemctl restart NetworkManager

It is a little something that I encountered. Hope you’ll this informative. Cheers!
