Hello,
I don't know if it is the case, but the kubuntu EFI bootloader (grubx64.efi) should be signed with a different certificate than the Debian Linux kernel.update-grub in Kubuntu works and adds Debian, but bad shim signature.... With Secure Boot disabled, Debian boots without problems, which means the problem is not Grub.
