how to restore a working network configuration with netplan on ubuntu 20.04

Hello. Newbie here.

recently I tried to install open nebula and for some reason,the eno1 network interface is disappeared from my ubuntu 20.04 network configuration and I would like to restore it,because actually I'm not able to connect to internet. Ubuntu 20.04 uses netplan. This is my 01-network-manager-all.yaml file :


version: 2

renderer: networkd



dhcp4: true

Actually,when I do ifconfig,I see these network interfaces :

docker0 : inet ; netmask ; broadcast

minione-nic : no inet ; no netmask ; no broadcast

veth03ad024 : no inet ; no netmask ; no broadcast

virbr0 : inet ; netmask ; broadcast

virbr0-nic : no inet ; no netmask ; no broadcast

I tried to re-create the old eno1 interface with these commands :

sudo netman apply

sudo systemctl restart network-manager

I don't see any identation error,but the situation is not changed. I have no eno1 interface and no connection to internet. what should I do ? what's missing ?

Is there anything regarding NICs in the kernel startup messages? Use dmesg or journalctl -k.
