He is most likely using armv7 and that comes with its own issues, ie cpu type and floating point (hard/soft, neon and simd). aarch64 much easier to build on.I'm using Debian armhf here on various machines (most of them with ARMv7 CPUs but some one of them with an ARMv8 CPU (and kernel)). I haven't encountered any particular problem (both in terms of using and installing Debian and in terms of "manually" building software from source) that seems related to ARMv7 vs ARMv8. Stefan
