[Quantal] [Regression] update-manager fails and exits if any source cannot be reached

[Swâmi Petaramesh]

Confirming immediately, as behaviour is consistent across 6 machines and more than a month.

In Quantal, update-manager immediately exits if any of the sources listed in /etc/apt/sources.list or /etc/apt/sources.list.d/* is temporarily unreachable, or if its package list update fails for whatever reason.

This prevents installing updates from working sources as soon as one, possibly minor, additional source fails. (and some minor sources do fail very often, such as http://download.virtualbox.org/virtualbox/debian that is a good example...)

This is a regression. Previous to Quantal, having one failing source didn't prevent from upgrading from other, working ones.
