Accidentally deleted /etc/resolv.conf and now can't access any domain

  • 772

I was getting dns probe finished message in chrome on Ubuntu 18.04 so I looked up on the internet and tried to run the following commands.

sudo rm/etc/resolv.conf
sudo ln -s /var/run/resolvconf/resolv.conf /etc/resolv.conf

Above 2 commands executed successfully but the following didn't.

sudo resolvconf -u

It gives an error message that resolvconf is not installed.

Now, nothing is working and /etc/resolv.conf file is empty. I'm not even able to edit it (I tried to a add nameserver 8.8.8.8).

Please help.

Edit: i'm still getting ERR_NAME_NOT_RESOLVE and here's the output of 'service --status-all`.

    To fix this you should recreate the link how it was. On 18.04 /etc/resolv.conf points to ../run/systemd/resolve/stub-resolv.conf.

    So to fix your problem it should be enough to do the following:

    sudo rm resolv.conf
sudo ln -s /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

  2. I had exactly the same issue and just removed the resolv.conf file by using the same commands! here is how I fixed it: if you are using gnome, then: sudo service network-manager restart this will recreate all the necessary files automatically.
