Hello,
I've tried upgrading my included kernel in 22.04 with a newer one from:
https://kernel.ubuntu.com/~kernel-ppa/mainline/
Unfortunately this does not work as it just throws an error on boot:
"error: bad shim signature.
error: you need to load the kernel first.
Press any key to continue..."
Could the kernels off this repo be signed so they can be used with secure boot?
I need a newer kernel to support hardware found in my ASUS G14 2022 model, specifically the keyboard back light.
