Kiwi-ng Secure Boot not working

Hi All,
I am trying to enable a secure boot in Ubuntu OvA image using kiwi-ng.
I sign the grubx64.efi and shimx64.efi and place them in the root folder in the below path. The build is fine with no errors, If I try to boot the image it works in legacy bios but not in the UEFI. Please help

usr/lib/grub/x86_64-efi-signed/grubx64.efi.signed
usr/lib/shim/shimx64.efi.signed

You forgot to explain what “does not work” means.

And you tagged this as “other” (meaning no supported openSUSE version) and then talk about Ubuntu.

This however is the openSUSE user helping user forum.
