我正在尝试维护 old-releases.ubuntu.com 的 rsync 镜像，当我 rsync /ubuntu/dists 目录时，我得到的结果与在https://archive.ubuntu.com/ubuntu/dists.当我访问https://old-releases.ubuntu.com/ubuntu/dists，我得到了我期望的版本。
从 rsync 路径中，我得到了 bionic、devel、focal、groovy 等，但在 https 路径中，我看到了 artful、breezy、cosmic 等。
您能否确认是否存在协议不匹配，或者我是否在某些方面犯了错误？
以下是我所看到的：
# rsync -av --delete rsync://old-releases.ubuntu.com/ubuntu/dists .

它基于 rsync 模块，而不仅仅是域本身。
