I'm new user on Ubuntu and I need your help.
I would like to configure DNS in
/etc/resolv.conf, so I used this command:
sudo nano /etc/resolv.conf
I changed my DNS server and it was OK but, after restarting, my changes to
/etc/resolv.conf were removed and the default configuration was restored.
I have tried the command below but it failed:
sudo chattr +i /etc/resolv.conf chattr: Opération non supportée lors de la lecture des drapeaux sur /etc/resolv.conf
in english: chattr : Operation not supported when reading flags on /etc/resolv.conf
What can I do?
