Hans, let me reiterate this: Maybe you had put another package from trixie/testing into packages.chroot, which depends directly or indirectly on grub-efi-amd64-unsigned? Possible packages in testing/trixie main are: - grub-efi-amd64-bin depends on grub-efi-amd64-unsigned - grub-efi-amd64 depends on grub-efi-amd64-bin - shim-signed depends on grub-efi-amd64-bin And debian-l...@lists.debian.org could be a good starting point for your problem.
