Failed to bring up eth1 - ifdown: interface eth1 not configured

[trompx]

Hello,

I am using Linux Mint 19.3.
I try to setup a eth1/eth2 interfaces with the following:

interfaces_ether_interfaces:
  - device: eth1
    bootproto: static
    address: 192.168.33.15
    netmask: 255.255.255.0
    gateway: 192.168.0.254
    dnsnameservers: 8.8.8.8 8.8.4.4
    mtu: 9000
  - device: eth2
    bootproto: dhcp

The [workstation/network : Bounce network devices] task triggers the following error:

fatal: [workstation]: FAILED! => {
    "changed": true,
    "cmd": [
        "nohup",
        "bash",
        "-c",
        " returncode=0  ifdown --allow auto eth1;  ifdown --allow auto eth2;  if ! ifup --allow auto eth2; then\necho \"Failed to bring up interface eth2\";\nreturncode=1\nfi;  if ! ifup --allow auto eth1; then\necho \"Failed to bring up interface eth1\";\nreturncode=1\nfi; exit $returncode"
    ],
    "delta": "0:00:00.062514",
    "end": "2020-06-16 14:30:19.033546",
    "rc": 1,
    "start": "2020-06-16 14:30:18.971032"
}

STDOUT:

Cannot find device "eth1"

I think it may come from missing entries in /run/network/ifstate which outputs:

lo=lo

Do I need to create a task to add my interfaces or your role is already supposed to do it and there is a bug?

Just found out Ubuntu 18.04 uses NetPlan now...
