Currently the browser receives:

You could try adding a Content-Disposition header to specify a file name:

  Content-Disposition: attachment; filename=APackage.tar.gz

In Apache you can (apparently [1],[2]) do it like this:

  RewriteRule "^packages/archive/[^/]+/[^/]+/(.+)$" - [env=pkgname:$1]
  Header set Content-Disposition "attachment; filename=\"%{pkgname}e\"" env=pkgname
