Hi, The below mentioned commands are useful. Hence we need to debug this further and establish further details about your setup.
1) which keys are in DB? ( mokutil --db --list-enrolled ) 2) which keys are used to sign grub image? ( sbverify --list grub*.efi ) 3) which keys are used to sign grub image? ( sbverify --list Image ) 4) since shim verifier was not disabled during grub mkimage build, which Shim did you compile, with what toolchain, and which keys was it signed with? 5) if you don't want to use Shim (and loose ability for users to enroll their own machine owner key, and revoke grub via sbat revocation - if underlying firmware can do those things i.e. secure edk2 builds), you must create grub image with disable shim lock verifier option. 6) if you do not want to sbsign kernel image using secureboot keys, you can alternative provide detached gpg signature and create grub image with a gpg public key built-in. 8) maybe there is some other way to verify kernel, i.e. you could implement a new verifier module that that use calls to a prior stage bootloader or firmware to verify kernel authenticity. 9) if you do not want to sign kernel at all in any way, you must disable secureboot at either firmware level (SecureBoot variable) or shim/grub/linux-only level (MokSBState see mokutil --disable-validation). Because if firmware SecureBoot is on, and mokutil validation is on, loading unverifiable kernels is not supported in grub 2.06 thanks to implementing lockdown. If the kernel is expected to be verifiable and yet fails to verify please provide further details. We have experienced buggy compilers, binutils, sbsign tooling which would produce invalid / unverifiable signatures in the past. Also we have seen buggy firmware that fail to verify correctly signed binaries.
