`Debian` 作为一个大的系统组织框架，其下有多种不同操作系统核心的分支计划，主要为采用 `Linux` 核心的 `Debian GNU/Linux` 系统，其他还有采用 `GNU Hurd` 核心的 `Debian GNU/Hurd` 系统、采用 `FreeBSD` 核心的 `Debian GNU/kFreeBSD` 系统，以及采用 `NetBSD` 核心的 `Debian GNU/NetBSD` 系统。甚至还有利用 `Debian` 的系统架构和工具，采用 `OpenSolaris` 核心构建而成的 `Nexenta OS` 系统。在这些 `Debian` 系统中，以采用 `Linux` 核心的 `Debian GNU/Linux` 最为著名。

`Ubuntu` 是一个以桌面应用为主的 `GNU/Linux` 操作系统，其名称来自非洲南部祖鲁语或豪萨语的“ubuntu”一词（官方译名“友帮拓”，另有“吾帮托”、“乌班图”、“有奔头”或“乌斑兔”等译名）。`Ubuntu` 意思是“人性”以及“我的存在是因为大家的存在”，是非洲传统的一种价值观，类似华人社会的“仁爱”思想。 `Ubuntu` 基于 `Debian` 发行版和 `GNOME/Unity` 桌面环境，与 `Debian` 的不同在于它每 6 个月会发布一个新版本，每 2 年推出一个长期支持 **（Long Term Support，LTS）** 版本，一般支持 3 年时间。

这并非系统不支持 `apt-get` 命令。Docker 镜像在制作时为了精简清除了 `apt` 仓库信息，因此需要先执行 `apt-get update` 命令来更新仓库信息。更新信息后即可成功通过 `apt-get` 命令来安装软件。
