Just got a new VPS running Ubuntu 11.04 and tried to update it. I got this error. I get the same error whenever using apt-get

If needed, here is my /etc/apt/sources.list

root@Rx:/etc# more /etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu natty main
deb http://archive.ubuntu.com/ubuntu natty-updates main
deb http://security.ubuntu.com/ubuntu natty-security main
deb http://archive.ubuntu.com/ubuntu natty universe
deb http://archive.ubuntu.com/ubuntu natty-updates universe

And if needed, I did a ping test:

root@Rx:~# ping -n 8.8.8.8

This is /etc/resolv.conf

root@Rx:~# more /etc/resolv.conf
nameserver 199.193.248.1

This is a DNS problem. What's in your /etc/resolv.conf? –  NathanG May 8 '12 at 2:26

Try adding a line in resolv.conf with nameserver 8.8.8.8. –  NathanG May 8 '12 at 2:37
    
@NathanG That did the trick! Want to make it an answer so I can accept? –  Kevin Duke May 8 '12 at 2:40
    
I did get these messages when running apt-get upgrade cryptsetup: WARNING: failed to detect canonical device of /dev/xvda1 cryptsetup: WARNING: could not determine root device from /etc/fstab but otherwise it seems to work good –  Kevin Duke May 8 '12 at 2:41

The problem is that the DNS server you had originally isn't responding to your queries. You can add another one to the list to check. 8.8.8.8 (provided by Google) is the easiest to remember.

Add the line nameserver 8.8.8.8 to your /etc/resolv.conf to query that server.

If the original server is one that the VPS provider gave you, you may want to bring this up with their support team - it's possible there's some sort of management tool that depends on it. Other than that, you can use 8.8.8.8 as your primary DNS forever.

I don't know much about this but the IP address of my VPS is different from the one in resolv.conf, is this a problem as well? –  Kevin Duke May 8 '12 at 2:52

The address(es) in your /etc/resolv.conf are your DNS resolvers. They have little to no relation to the IP address of your server. –  EEAA May 8 '12 at 2:53
    
> Add the line nameserver 8.8.8.8 to your /etc/resolv.conf to query that server. sudoedit /etc/resolv.conf Thank you!!! This worked perfectly. –  user138034 Sep 22 '12 at 16:50
