I agree, there is at least one other bug report (marked it as a duplicate of this one) where the user was left hanging for a long while without knowing what is going on. Maybe a shorter time-out would be nice.
I don't know how well the Retry button idea would work, though, because the installer is already doing that behind the scenes, trying out different mirrors (or at least, it should be doing that...).
