I was debugging Android Studio projects on my Nexus 5 for several months without any problems. I then installed Kali Nethunter and now there's no way I can debug my program. I tried reinstalling the drivers, unplugging-plugging, adb kill-server and start server. USB debugging is allowed, but I can't get the check authorization window.
adb devices says that my device is unauthorized
Okay, yeah its Kali issues..
Supposed workaround is here:

Last message is probably the bet workaround to try first..if you do not have a 2nd real device use an emulator and follow the same directions
