Solution 1

This issue was posted about 2 years ago but I wanna answer this problem so no one should have difficulty like me.

First open /etc/resolv.conf

(if you using Ubuntu distributions, the file is /etc/resolvconf/resolv.conf.d/head)

# cat /etc/resolve.conf

And after that, write this rows to the file:

# Google's public DNS servers
nameserver 8.8.8.8    # Primary DNS server
nameserver 8.8.4.4    # Secondary DNS server

These are the Google's public DNS servers as mentioned in the code above.

Save and close.

After restart the network service using this command:

service network restart

This solved my problem.

Hope help to others...

Solution 2

In my case was a dns misconfiguration in Vagrant VM.

Updating DNS in /etc/resolv.conf solved my issue: https://askubuntu.com/questions/897270/dns-cannot-resolve-hosts

hope this will help other users

Solution 3

I fixed the issue on Linux/Centos6 (Plesk Onyx) by:

Opening /etc/resolv.conf (my file was empty)

Added: nameserver 8.8.8.8 nameserver 8.8.4.4

options rotate options timeout:3

Hopefully this helps someone out there.
