UnboundLocalError: local variable 'ifindex' referenced before assignment
This is with network-manager taking control over the whole network
management rather than networkd.
Steps to reproduce:
1. Enter console-conf
2. Configure DHCP for ethernet and hit the done button
3. Once network is configured and you're on the sign-on page hit the "cancel"
button which takes you back into the terminal where you have to hit enter to
start console-conf again.
4. Hit enter and see console-conf crashing
