据我所知，输入“apt install some-package”会安装软件包、依赖项和推荐软件包。如果我使用 --no-install-recommends 标志，那么只会安装软件包及其依赖项。

这与这个问题因为我想知道为什么推荐软件包列表会发生变化。

答案1
Apt 有三个等级的依赖关系：
depends：此包是必需的。没有其他办法。recommends：此包是可选的，但强烈建议使用以获得完整功能。suggests：此包可选添加一些额外的功能。
您的 Ubuntu 系统的默认设置包括depends和recommends软件包（不包括suggests）。您可以使用以下可选的 apt 标志更改这些设置：
--no-install-recommends
--install-suggests
有关这些选项的完整讨论，请参阅man apt-get。
答案2
依赖关系解析以递归方式进行，因此将建议视为依赖关系将会引入更多具有依赖关系的包。
因此，推荐软件包的列表发生了变化，因为不再包含命令行上列出的软件包推荐的软件包。
这也可能导致需要额外的软件包，例如，如果一个软件包有Depends: xterm | x-terminal-emulator，另一个软件包有Recommends: gnome-terminal，那么在没有建议的情况下进行解析将不会引入gnome-terminal，而这本来会满足x-terminal-emulator，所以xterm如果没有安装其他终端仿真器，那么也需要。
