Cut /etc/network/interfaces down to the lo stanza # The loopback network interface auto lo iface lo inet loopback Remove EVERYTHING else. Use Network Manager / nmtui / nmcli to build back what you need slowly If you have interfaces mentioned in /etc/network/interfaces - the old way - you will face problems. Hand editing the files is probably not the way to do this any more. > Hope this helps, With every good wish, as ever, Andy Cater
