Auto Updates stop on downloading

WordPress Automatic Upgrade & Plugin Central, both get to the downloading updates screen. A few seconds later it displays “done” then nothing happens. Nothing is actually downloaded, so of course the updates can not proceed anyways.

So, why are they saying “downloads complete”? & Why aren’t they downloading anything?
Do I need to modify some php code somewhere?

I have searched through the posts in vain.

I have years of experience with PC’s & coding but the answer to this problem eludes me.

Have a great day everyone!
