vanilla 5.4.249 : Secured boot

Hello,

Thanks to the huge help I got in the grub mail list, grub is now booting under secure boot.

I had 2 problems:

1. The shim packages I had are for i386 not amd64. So I installed the right shim packages.

2. I had to run grub-install under knoppix 9.1 which was booted in secure boot=enable in BIOS.
Till I did it, I got the following warning:

grub-install: warning: EFI variables are not supported on this system.

Thank you,
Zvika

Hello,

According to the following link:

The "EFI variables are not supported on this system" can be fixed by running:

modprobe efivarfs
mount -t efivarfs efivarfs /sys/firmware/efi/efivars

According to few links I found, the cause is that Knoppinx (in my case) is booting from USB stick.

Thank you,
Zvika
