apt-get自动删除所有内容

Question

我跑了13.10。我删除了emacs，然后运行sudo apt自动删除，但是它决定它需要删除所有这些东西(我可能需要很多东西)。以下是完整的清单：

Use 'apt-get autoremove' to remove them.

我再次尝试安装和删除emacs，但它仍然坚持我删除所有这些。libreoffice和python以前一直在这里，直到我将它们设置为手动安装为止。为什么Ubuntu想要删除所有这些？

Answer 1

您认为需要的任何包只需执行以下操作：

sudo apt-get install package-you-need

这样，您就可以将包标记为手动，然后可以自动删除。

Answer 2

不用担心，你不需要他们，

sudo apt-get autoremove

自动删除用于删除自动安装以满足某些包的依赖关系且不再需要的包。
