Comment 14 for bug 128165

After the automatic configuration of network, Ubuntu should test the Internet or we need change the timeout of apt.

A Sample:
when trying download packages from security.ubuntu.com, and Ubuntu see that security.ubuntu.com was unreachable, why Ubuntu try download other packages from the same domain ?
if the user has a bad network configuration like me, it will spend many hours,

i hope that a day someone fix this bug to make Ubuntu work in a bad system as well as in a good system.
