The zstd library does not support stream decompression, and it requires the zstd header to contain extra metadata, that the kernel build does not append: $ file -k vmlinuz-6.13+unreleased-cloud-arm64 vmlinuz-6.13+unreleased-cloud-arm64: PE32+ executable (EFI application) Aarch64 (stripped to external PDB), for MS Windows, 2 sections\012- data $ ukify build --linux vmlinuz-6.13+unreleased-cloud-arm64 --initrd /boot/initrd.img-6.12.12-amd64 --output uki Kernel version not specified, starting autodetection 😖.
