## I use ubuntu 20.04 and unfortunately non of the other answers worked for me so I share the way I fixed this problem
first install resolvconf if not installed
sudo apt update
sudo apt install resolvconf
check resolvconf service started and enabled
sudo systemctl status resolvconf.service
if service is not enabled you can start and enable it with :
sudo systemctl start resolvconf.service
sudo systemctl enable resolvconf.service
now edit resolv.conf.d/head configuration file
sudo nano /etc/resolvconf/resolv.conf.d/head
##add your DNS addresses to this file for example I use (8.8.8.8 and 8.8.4.4)
nameserver 8.8.8.8
nameserver 8.8.4.4Copyright © 2021 Codeinu
