Hi, I have a Intel NUC DE3815TYBE system and I have updated it without problems from Stretch to Buster (thanks to the developers!).
To activate Secure Boot[1], I have followed these steps[2]: * Confirm that shim-signed, grub-efi-amd64-signed and linux-image-4.19.0-5-amd64 packages are intalled * Reboot and enable Secure Boot (Standar mode) in BIOS * Reboot and check if Secure Boot is enabled In the kernel log appears as enabled: [...] kernel: secureboot: Secure boot enabled kernel: Kernel is locked down from EFI secure boot; see https://wiki.debian.org/SecureBoot [...] But mokutil says there's no support for Secure Boot: # mokutil --sb-state This system doesn't support Secure Boot Also with bootctl: # bootctl status | grep -i 'secure boot' Secure Boot: disabled I would like to know if I have enabled Secure Boot correctly or if I have made a mistake. Thank you in advance.
