After a power cycle, I'm unable to see my ethernet interfaces in ifconfig with the following netplan configuration. ethMine shows up in ip link show, but is not upped.

$ cat /etc/netplan/01-netcfg.yaml 
network:
  version: 2
  renderer: networkd
  ethernets:
    enp38s0f1:
      addresses: [192.168.1.21/24]
      match:
        macaddress: 80:fa:5b:xx:xx:xx
      set-name: ethMine
      nameservers:
        addresses: [8.8.8.8, 8.8.4.4]
      optional: true
  vlans:
    ethMine.200:
      id: 200
      link: ethMine
      addresses: [192.168.1.121/24]
  wifis:
    wlx7ca7b0bbf9f1:
      addresses: [10.10.10.15/24]
      gateway4: 10.10.10.1
      nameservers:
        addresses: [8.8.8.8, 8.8.4.4]
      access-points:
        "myssid":
          password: "mypasswd"
  • On Ubuntu desktop.
  • There are no other netplan configs.
  • /etc/network/interfaces is commented out
$ dmesg | grep ethMine
[    2.881002] r8169 0000:26:00.1 ethMine: renamed from enp38s0f1

On reboot, I see ethMine in ip link show, but it is not up and visible in ifconfig. ethMine.200 does not exist.

systemd logs:

sudo systemctl restart systemd-networkd causes ethMine to be upped, but still no vlan with logs:

netplan.io version in Ubuntu 18.04.4 LTS desktop:

$ dpkg -s netplan.io | grep '^Version:'
Version: 0.99-0ubuntu3~18.04.3

These manual steps work post boot:

sudo ip link set enp38s0f1 down
sudo ip link set enp38s0f1 name ethMine
sudo ip link set ethMine up
sudo ip addr add 192.168.1.21/25 dev ethMine

sudo ip link add link ethMine name ethMine.200 type vlan id 200
sudo ip addr add 192.168.1.121/26 dev ethMine.200
sudo ip link set dev ethMine.200 up

/etc/network/interfaces should look like this...

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

/etc/netplan/01-netcfg.yaml should look like this...

network:
  version: 2
  renderer: networkd
  ethernets:
    enp38s0f1:
      addresses: [192.168.1.67/24]
      gateway4: 192.168.1.1
      match:
        macaddress: 80:fa:5b:7d:94:8f
      #set-name: ethMine
      nameservers:
        addresses: [8.8.8.8, 8.8.4.4]
      optional: true
  vlans:
    ethMine.200:
      id: 200
      link: enp38s0f1
      addresses: [192.168.1.167/24]
  wifis:
    wlx7ca7b0bbf9f1:
      addresses: [10.10.10.15/24]
      gateway4: 10.10.10.1
      nameservers:
        addresses: [8.8.8.8, 8.8.4.4]
      access-points:
        "myssid":
          password: "mypasswd"

sudo netplan --debug generate

sudo netplan apply

reboot
