Ubuntu 18.04 server unable to ping websites but can ping IP addresses












0















Total newbie here, got fed up with Windows world and gone over to the dark side



Yesterday I installed Ubuntu 18.4 LTS on VirtualBox with bridge connections.



It seems I can ping IP addresses internally, ping with IP addresses externally but when I try to resolve hostnames or websites, I can't.

It seems that your server is trying to use IPV6 while it might be unproperly configured. You could try disable ipv6 if not used or check your ipv6 configuration.

    Check the answer from olivierb2. If still doesn't work, maybe is a problem of /etc/resolv.conf



    user@ubuntu:~$ sudo mv /etc/resolv.conf /etc/resolv.conf.bak
