Raspberry Pi OS ships a 64-bit kernel with a 32-bit userland, so uname -m - and
therefore ansible_architecture - reports aarch64 on a box whose /bin/ls is
ELF32 ARM and which has no /lib/ld-linux-aarch64.so.1. The aarch64 uv tarball
unpacked happily and then failed three tasks later with
/usr/local/bin/uv: No such file or directory
which is the dynamic loader missing, not the file, and points at entirely the
wrong thing. Pick the target triple from ansible_userspace_bits instead, which
is the fact that tells the truth, and key the install directory on the triple as
well as the version - otherwise `creates:` would keep a wrong-architecture
binary in place forever. Then run `uv --version` right after installing it, so a
bad download fails where the cause is visible.
