I can't get it work, any issues? I use Ubuntu 10.04.
While Ubuntu 10.04.4 LTS (Lucid Lynx) Server is still under support, until April 2015, you need to be planning when you transition to 12.04 LTS.
Your current problem:
This appears to be a 'temporary' issue. You should retry the next day.
Do you have the server configured to automatically receive security updates?
When did you last 'manually' (and successfully) get updates?
You may be experiencing issues with the GPG key for Lucid 'backports' and/or other outdated content. A less 'aggressive' configuration, less extra packages and other add-on elements, may be more stable and generally succeed.
