I am getting errors when running apt-get update or when installing new packages. Although this only happens when the server configured for a static IP address. Changing the configuration back to DHCP and restarting networking fixes the problem, although I want a static IP. Once it is working I can change back to my static IP address and restart networking. Although this only works until I restart the server (restarting the router is ok), and then I start getting the same errors and have to switch back to DHCP.

Any ideas on what could be causing this or tips on troubleshooting it? Thanks in advance.

• here is my static IP configuration:

  auto eth0
  iface eth0 inet static
      address 192.168.2.2
      netmask 255.255.255.0
      gateway 192.168.2.1
  

• The apt-get update errors go something like this:

  A few of these

  Ign http://us.archive.ubuntu.com precise-backports InRelease
  

  then a lot of these

  Err http://security.ubuntu.com precise-security Release.gpg   Something wicked happened resolving 'security.ubuntu.com:http' (-5 - No address associated with hostname)
  

  and a lot of these
