Public bug reported: Now that 17.10 has migrated to netplan+systemd-networkd+systemd-resolved by default, ubuntu-fan autopkgtests are failing; at least one reason for this failure is wrong detection of the default network interface because autopkgtest environments appear for some reason to be getting multiple default routes:
