I have Ubuntu 20.04 LTS with Kernel 5.4.0-42-generic. Then updated kernel to hoping that 5.8.2-050802-generic hoping by Bluetooth device will work with this .(As you mentioned this script is accepted in 5.7 and 5.8 version of kernel) With new kernel 5.8.2-050802-generic, it detects logitech M337 mouse , but not able to configure. Then I tried above script and got error cp: cannot stat '/usr/lib/modules/5.8.2-050802-generic/build/.config': No such file or director -- You are receiving this mail because: You are the assignee for the bug.
