- **`${repository_root}/`**
> 取決於如何設定 packages repository 以及在 server 上的實際路徑；在 `/etc/apt/sources.list` 裡
> ```
> deb uri distribution [component1] [component2] [... ]
> ```
> 的 **`uri`** 指定了 repository_root。例如
> ```
> deb https://deb.debian.org/debian stable main contrib non-free

> 中的 `https://deb.debian.org/debian` 就是 repository_root。
- **`dists/`**
- **`${distribution}/`**
> **Release** 如 `stable`、`testing`、`unstable`、`sid`，**suite** 如 `sid`、`stable`、`testing`、`unstable`，或 **codename** 如 `bookworm`、`bullseye`、`buster`；可自定義但不建議。
- **`Release`**
> Repository 的 metadata，例如 packages list、components、checksum for the indices。
- **`Release.gpg`**
> OpenPGP signatures。
