** Description changed: ## DRAFT ## [Impact] "netplan ip leases <interface>" command is failing with a Traceback[1] when specifying an interface non-existing on the system. non-dhcp configured or non configured with netplan.

[Test Case] * Performed the command "netplan ip leases <INTERFACE>" on a Bionic/18.04 LTS system with netplan installed. If interface is non- existent, not configured in netplan or not set to DHCP, it will generate a Traceback[1] instead of displaying an error message with some explanation as of why it fails. Otherwise it will succeed as follow : $ netplan ip leases eth0 # This is private data. Do not parse.
