不知何故，我设法卸载了一些不该卸载的东西。
当我重新启动时，登录屏幕正常显示，但之后桌面变黑（虽然有一些图标，我可以启动那些程序），没有启动器，也无法打开终端窗口。
在文本界面 ( Alt++ ) 上，我重新安装了Ctrl，它让我恢复了 GUI，但现在它看起来有点过时，并且处理方式不同（例如，++打开一个终端窗口，但没有聚焦）。并告诉我，有许多未使用的依赖项（见下文）。F1unityCtrlAltTapt
你知道我无意中删除了哪个包吗？我可能还需要记住其他什么吗？
非常感谢。

Use 'sudo apt autoremove' to remove them.
答案1
虽然该unity软件包足以满足 Unity 窗口管理器、桌面合成器和基本窗口主题的需求，但它不包含或依赖于整个 Ubuntu 桌面。要恢复它，您需要安装该ubuntu-desktop软件包：
sudo apt install ubuntu-desktop
注销你的图形用户会话并重新登录，然后一切就绪了。
可能会有一些挥之不去的影响：update-alternatives系统可能在删除某些软件包后选择了下一个最佳替代方案。当您重新安装它们时，它们通常会恢复如果他们的替代方案具有更高的优先级。如果它们具有相同的优先级值，则先前的设置将保持有效。
