"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.
- Reproduced using:
- ii netplan.io 0.36.1 amd64 YAML network configuration abstraction for
various backends
-
- Of course, the cmdline works as expected when the interface exist[2]
-
- IMHO, if someone enter in the above scenario, netplan should just output
- a generic error saying that the interface cannot be found or else,
- instead of printing a stack traceback.
-
- [1[ - Non-existing interface
-
- $ netplan ip leases eth1
+ [1] $ netplan ip leases eth1
Traceback (most recent call last):

- [2]Exsiting interface
+ [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
