If you encounter this error while trying to upgrade your installation (through the console), try this:


  1. from the console,, try pinging data.alienvault.com ( - it should certainly work;
  2. check your /etc/hosts file for that location - if it doesn't exist, update the record;
  3. restart your networking service;
  4. try upgrading the system again - you should now see the system doing the update / upgrade procedure.
