# Neither spotifyd nor librespot is in Debian bookworm main, so this hook tries apt
# first (in case a backport/third-party repo has been added) and otherwise stops at a
# documented placeholder. No release URL is hardcoded on purpose: pinning a version
# here would silently 404 the moment upstream moves a tag, which is worse than an
# explicit "do this by hand" message.
