我正在运行 13.10。我删除了 emacs，然后运行了 sudo apt-get autoremove，但它决定需要删除所有这些其他东西（其中很多我可能需要）。以下是完整列表：

Use 'apt-get autoremove' to remove them.
我尝试再次安装和删除 emacs，但它仍然坚持要求我删除所有这些。libreoffice 和 python-twisted 曾经在这里，直到我将它们设置为手动安装。为什么 Ubuntu 要删除所有这些？
答案1
如果您认为需要任何包，只需执行以下操作：
sudo apt-get install package-you-need
这样，您可以将包标记为手动，然后可以执行自动删除。
答案2
不用担心，你不需要它们，
sudo apt-get autoremove
Autoremove 用于删除那些为了满足某些包的依赖关系而自动安装的、不再需要的包
