I just followed the instuctions from this post:

How to enable netplan on ubuntu server upgraded from 16.04 to 18.04

I added the following lines in to the config file: /etc/netplan/config.yaml (I had to install netplan and create the folder manually.) network: version: 2 renderer: networkd ethernets: eth0: dhcp4: true

But unfortunately I installed netplan instead of neplan.io.

After reboot, I lost every connection with my Odroid.

Server version
Netplan wasn't installed
There is no Wi-Fi hardware.

If I install netplan.io, will my odroid connect to the Internet again?

Edit:

dpkg -l netplan: enter image description here

cat /etc/network/interfaces: enter image description here

cat /etc/netplan/*.yaml: enter image description here

sudo lshw -C network: enter image description here

sudo apt install netplan.io: enter image description here

After trying to install netplan.io we purged netplan. My brother will send the odroid to me then I fight further.

  • Is this a desktop or server installation? If you upgraded to 18.04, netplan should have already been there. Edit your question and show me dpkg -l *netplan*. Are you able to make a wireless Internet connection? – heynnema May 7 at 15:54
  • Also show me cat /etc/network/interfaces and cat /etc/netplan/*.yaml. – heynnema May 7 at 15:59
  • Hello, thank you for help me. The odroid is 700km away from me I will try it on the weekend, with my brother! – Beatr May 7 at 16:06
  • Is the problem on your PC, or your odroid? Is it a server or desktop installation? – heynnema May 7 at 16:53
  • I edited the quedtion, it is a server on my odroid c2 – Beatr May 7 at 19:00

renderer: networkd is used in server installation.

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: true

For desktop netplan uses renderer: NetworkManager and config looks like this /etc/netplan/01-network-manager-all.yaml

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

You can generate it (but need to remove /etc/netplan/config.yaml before)

sudo netplan --debug generate
sudo netplan apply
reboot
