How do which sites I have selected affect updates?

Question

Does it matter what site you choose for updates?

Do you get the same updates no matter what site you choose?

Answer 1

I assume that you refer to the repositories when you refer to 'site'
(The thing you select from 'software sources')

The differences may be:

• Speed. Mirrors close to your physical location usually serve updates at slightly greater speed.
• Time: At times, there is a delay between synchronizations, so you may get updates a little later, depending on the mirror you choose.

That said, All repositories are periodically synchronized to have Exactly the same content. So It really doesn't matter what repo you choose.

As a side note, This QA thread has information on how to choose a mirror to maximise download speed.
