Outdated non_OSS & openSUSE Backport repos

‘zypper dup’ wants a different mirror for these two repos.
The URLS in YaST list as $releasever
where do I look for them?
Trying to update my wifes laptop from 15.3 to 15.4 and no go!

On top of all, it removed the WiFi dongle drivers, and installed something that will not recognize WiFi ( onboard nor dongle).

I STOPPED upgrade from the USB key. I got tired of 'conflict resolutions after about 600, so I am doing a fresh install.
next 2 days getting things back in so my Wife can use her machine.

Disregard everything in the previous posts. A fresh install and ready to go.
