knowledge on this subject), I am now facing "invalid signature" error when I reboot with my installed dev kernel.
When/where exactly are you getting that error? There's three major places where things can go wrong:
I believe just after you select which kernel you wish to boot into. Check below: https://www.youtube.com/watch?v=bsCyZlLgrUY
1) If you're using secure boot, and the grub2 stuff isn't signed by a certificate your BIOS/EFI knows about.
2) If you're using secure boot, and the kernel itself isn't signed by a certificate that grub2 knows about.
3) If your kernel config says modules have to be signed, and a module isn't properly signed with a certificate that your kernel knows about. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
