It looks like your Droplet is having trouble looking up domain names, possibly because the DNS resolvers are misconfigured. Can you post the output of these two commands?

cat /etc/resolv.conf
sudo netstat -plutn | grep :53

    cat /etc/resolv.conf
    root@ubuntu:/home/jorge# cat /etc/resolv.conf

    # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)

    DO NOT EDIT THIS FILE BY HAND – YOUR CHANGES WILL BE OVERWRITTEN

    nameserver 8.8.8.8

    netstat -plutn | grep :53
    root@ubuntu:/home/jorge# netstat -plutn | grep :53
