But you have control over the script that working your installation, and you
can choose a mirror that is likely working. I.e. kernel.org mirrors.

It knows all of them and all of them are good for it.
If you know better, then it's up to you to tell it that.

Now, this is a more useful information. But still not quite enough to track
the problem.
If you are familiar with GDB, you can try debugging the execution and see why
it crashes.

So, do that. I see no stopping for it.
As Brian pointed out, the list of mirrors is publicly available.
