Comment 12 for bug 24250

I still don't think that the gnome proxy settings should be what update-manager should look at for several reasons:

1. I might run update-manager with root permissions (remember: I might even do this without a proper intention, because all the update tools need superuser priviliges) - then there's no way to access the gnome proxy settings of the user anymore
2. The technical reason: update-manager serves (in a rough view) as a front-end to apt. Listening to the gnome proxy settings is nice, but as long as the apt-settings are not correct (or - by mistake or intention - apt and gnome have different proxy settings), update-manager should still use exactly the same mechanism as apt does.

Use case: set up a local apt proxy for Ubuntu and use an http proxy to forward all apt-requests to is, but the default web access is provided by the plain router setup.
