What it ultimately comes down to is this is a group of volunteers.
None of them want to have to try to explain or fix a broken setup on a user's
system caused by a broken mirror: they don't have the time.
So if there is any chance of setup breaking an install, setup will quit before
it does any damage.

Whether setup lets you know in a dialogue box or in a log file, that it upgraded
or failed to upgrade your installation, may depend on your install options.

Personally, I would be very happy if setup popped up the setup log at the end of
the run, if there were any issues. I have done this kind of results display in
Windows and Unix command line and GUI environments for user and developer tools:
launch a log viewer if there was a problem, launch an app if results are good.
