What DNS servers are you using? Open "System Settings" and go to "Network". You can change DNS servers from there. Your ISP should have servers that you can use, but you can also try something else. I know that Google has two servers at 8.8.8.8 and 8.8.4.4 that work for me.



To debug DNS issues you can use dig and ping. Try these commands:



dig <some-domain.com>

ping <DNS-server-IP-address>


The values could be, for example:



 dig ubuntu.com

 ping 8.8.8.8


If changing DNS servers doesn't work, post the output of the above commands here.
