It would be more conventional to fix, then close :) Maybe
clean_cache [1] Whether to flush obsolete versions of packages from your cache daily. It should be safe to leave this on. A package version is not obsolete if any of the distributions (stable, testing, etc) or architectures you use reference it. My original question referred to "releases", but I think the proper Debian term is "distributions." Maybe in the discussion of clean_cache, or somewhere else (package description or README.Debian?), caution that "distribution" does not mean Debian vs. Ubuntu. I've tried to word it without requiring knowledge of the internals (e.g., referring to debs or Packages.gz). I added "versions" since, I assume, it's particular debs that are flushed, not the whole package in all its forms. It's good news that apt-cacher supports multiple distributions.
