Hi, First if we bump ABI could we target "pABI v0" aka amd64 baseline instead of only SSE2 ? It is perfectly equivalent (except minor point about FXSR). Moreover you could test cpu support using this https://wiki.debian.org/InstructionSelection#Isa_support_package I have made qemu-good qemu-bad wrapper to test if needed In this case, for your user I will add a wrapper that at preinst time warn user about unsupported instrution for next debian version and backport to bookworm PU I suppose dpkg could be made pre depends on this wrapper and we could break the upgrade if instruction is not supported Bastien
