注意：最初发布的问题询问 Ubuntu他们善意地指出这个 StackExchange 更适合非官方的 Ubuntu 衍生品。
背景信息。
当前运行 POP_OS 20.04
mousepad当操作系统版本为 18.10 时安装文本编辑器，并在升级到后续操作系统版本的过程中将其用作默认文本编辑器。我现在正在运行 Pop_OS 20.04 LTS，发现它gedit对于基本文本编辑来说效果很好。现在准备删除mousepad（如果安全且可能的话，还可以删除任何不必要的依赖项）。
已设置gedit为默认文本编辑器。
第一次尝试通过 POP Shop 卸载mousepad0.4.2（deb 版本）会出现以下错误，
卸载“鼠标垫”失败
This may have been caused by external or manually compiled software.
The following packages have unmet dependencies:
gir1.2-gtksource-3.0: Depends: libgtksourceview-3.0-1 (>= 3.23.90) but it is not going to be installed
使用命令行查看删除鼠标垫（仅）给出以下信息，
sudo apt remove mousepad
0 已升级，0 是新安装，1 是删除，0 是未升级。
执行此操作后，将释放 1,612 kB 磁盘空间。 （暂时中止）
然后查看mousepad使用命令的删除和依赖项，
username@computer:~$ sudo apt autoremove mousepad

Do you want to continue? [Y/n] (aborted for now)
我可能可以只删除mousepad(1,612 kB)，但肯定希望删除价值 787 MB 的 324 个显然不再需要的依赖项。然而，考虑到返回的信息量没有足够的知识和经验来告诉终端“是” - 请删除这些。
问题：删除这些依赖项真的基本上是安全的，不会导致灾难性问题吗？如果没有的话，我很想知道这里发生了什么......
到目前为止，我们已经了解 autoremove 命令只会删除不再需要的依赖项（可以安全卸载），但这种假设可能不正确。
答案1
sudo apt autoremove 不会破坏任何东西或删除其他包所需的依赖项。
使用鼠标垫的额外参数运行它，
sudo apt autoremove mousepad只会将鼠标垫及其独特的依赖项添加到要删除的孤儿列表中。
