Intel Wireless 8265 / 8275 [8086:24fd] subsystem [8086:9010] WiFi won't connect, but kernel 5.6 fixes it

[Dennis Burrows]

My wifi adapter won't connect under Kubuntu. It works fine when I boot the same laptop under Ubuntu 18.04, but when I boot under Kubuntu 20.04, I get "Configuring Interface" followed by "Wireless interface (wlp1s0) The wifi network could not be found."

It worked fine up until today. Ethernet connection works fine.

I tried restarting NetworkManager.service in systemctl and I get this:
