@karcaw Are you running on Ubuntu 20? When I try this on my Ubuntu 18, I get:

root@c910f04x12v05:~# netplan get ethernets.ens3.dhcp4
usage: /usr/sbin/netplan  [-h] [--debug]  ...
/usr/sbin/netplan : error: argument : invalid choice: 'get' (choose from 'help', 'apply', 'generate', 'ip', 'try')
root@c910f04x12v05:~#

yes i have been running ubuntu 20.04 and 22.04 for this issue.

Since xCAT still needs to support UB 16, 18, is there a version of this command that would run on all of them ?

@karcaw
Can you show the output you are getting from netplan get command ?
I still get /usr/sbin/netplan : error: argument : invalid choice: 'get', even when running on Ubuntu 20.04

I just get a false or true result:

--> netplan get ethernets.enp0s25.dhcp4 
false

What version of netplan do you have installed ? I have:

root@c910f04x35v07:~# apt list --installed | grep "netplan"
libnetplan0/now 0.99-0ubuntu3~20.04.2 amd64 [installed,local]
netplan.io/now 0.99-0ubuntu3~20.04.2 amd64 [installed,local]
root@c910f04x35v07:~#

@gurevichmark What needs to happen to move this merge request forward?

Need a set of flags or something, so that netplan get works on UB16, UB18 and UB20.
Currently I get /usr/sbin/netplan : error: argument : invalid choice: 'get', when running on those versions of OS.
Seems like netplan get only works on UB22.
