** 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. + "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. [1] $ netplan ip leases eth1 Traceback (most recent call last): File "/usr/sbin/netplan", line 23, in <module> netplan.main() File "/usr/share/netplan/netplan/cli/core.py", line 50, in main self.run_command() File "/usr/share/netplan/netplan/cli/utils.py", line 130, in run_command self.func() File "/usr/share/netplan/netplan/cli/commands/ip.py", line 56, in run self.run_command() File "/usr/share/netplan/netplan/cli/utils.py", line 130, in run_command self.func() File "/usr/share/netplan/netplan/cli/commands/ip.py", line 75, in run self.run_command() File "/usr/share/netplan/netplan/cli/utils.py", line 130, in run_command self.func() File "/usr/share/netplan/netplan/cli/commands/ip.py", line 142, in command_ip_leases out = subprocess.check_output(argv, universal_newlines=True) File "/usr/lib/python3.6/subprocess.py", line 336, in check_output **kwargs).stdout File "/usr/lib/python3.6/subprocess.py", line 418, in run output=stdout, stderr=stderr) subprocess.CalledProcessError: Command '['/lib/netplan/generate', '--mapping', 'eth1']' returned non-zero exit status 1. [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. ADDRESS=10.104.180.111 NETMASK=255.255.255.0 ROUTER=10.104.180.1 SERVER_ADDRESS=10.104.180.1 NEXT_SERVER=10.104.180.1 BROADCAST=10.104.180.255 T1=1673 T2=3023 LIFETIME=3600 DNS=10.104.180.1 DOMAINNAME=lxd HOSTNAME=nplan CLIENTID=ffefc0b3c900020000ab118611d41fefa41121 [Regression Potential] + 'netplan ip leases' is used as informational only, so failures with it should be considered a low priority issue. Nevertheless, failures to properly parse the data from the networking backends, experienced as tracebacks (like the one this is supposed to fix) or as invalid data / incomplete data being shown on screen should be investigated as potential regressions. + [Other Info] * Netplan PR: - https://github.com/CanonicalLtd/netplan/pull/25 The above PR will output "Interface <INTERFACE> is not managed by netplan or not configured for DHCP" Example: $ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 - link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 - inet 127.0.0.1/8 scope host lo - valid_lft forever preferred_lft forever - inet6 ::1/128 scope host - valid_lft forever preferred_lft forever + link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 + inet 127.0.0.1/8 scope host lo + valid_lft forever preferred_lft forever + inet6 ::1/128 scope host + valid_lft forever preferred_lft forever 45: eth0@if46: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 - link/ether 00:16:3e:91:0d:24 brd ff:ff:ff:ff:ff:ff link-netnsid 0 - inet 10.104.180.139/24 brd 10.104.180.255 scope global dynamic eth0 - valid_lft 3422sec preferred_lft 3422sec - inet6 fd42:ad0:706e:4129:216:3eff:fe91:d24/64 scope global dynamic mngtmpaddr noprefixroute - valid_lft 3497sec preferred_lft 3497sec - inet6 fe80::216:3eff:fe91:d24/64 scope link - valid_lft forever preferred_lft forever - + link/ether 00:16:3e:91:0d:24 brd ff:ff:ff:ff:ff:ff link-netnsid 0 + inet 10.104.180.139/24 brd 10.104.180.255 scope global dynamic eth0 + valid_lft 3422sec preferred_lft 3422sec + inet6 fd42:ad0:706e:4129:216:3eff:fe91:d24/64 scope global dynamic mngtmpaddr noprefixroute + valid_lft 3497sec preferred_lft 3497sec + inet6 fe80::216:3eff:fe91:d24/64 scope link + valid_lft forever preferred_lft forever $ netplan ip leases eth1 Interface eth1 is not managed by netplan or not configured for DHCP $ netplan ip leases eth2 Interface eth2 is not managed by netplan or not configured for DHCP $ netplan ip leases eth0 # This is private data.
