我有一些奇怪的未满足的依赖项，我尝试了所有方法来修复它们。以下是 sudo apt-get dist-upgrade 的输出。

例如第一个 freeglut3 ：依赖：libgl1-mesa-glx 或 libgl1 我已经安装了 libgl1-mesa-glx。我很确定我已经安装了所有依赖项，但它说没有。我不知道该怎么办。

您正在尝试从较新的存储库安装软件包，但无法访问具有较新依赖项的存储库。编辑 /etc/apt/sources.list 文件

这是 /etc/apt/sources.list 文件的示例，也可以从 unity 转到软件和更新并删除非关键存储库，然后执行
sudo apt-get update
sudo apt-get install -f
sudo dpkg --configure -a
我强烈建议从您的 sources.list 中删除不同版本的存储库 - 正如其他人已经说过的，这是导致系统崩溃的原因（使用首选项文件，您可以管理一些混合，通常避免混合版本是一种很好的做法）。
