How do I change which mirror I get updates and software from?

How do I select which server Ubuntu will get it's software and updates from? I know how to find the list of mirrors on the web, but not how to use them.

Solution 1:

Quite easy:

• Open the Software & Updates (you can also start this using the software-properties-gtk command)

• Find the Download From dropdown and select Other

  

• Choose the server you want:

  

  If you click Select Best Server, the USC will go through a load of tests to find the server that's fastest in your location. Generally it will be a server close by.
