在检查 Synptic 时很清楚：

试图将特定版本强制回退到 10.5.2 似乎表明它将安装很多我已经很好配置的东西：

简单的解决方案可能是

libglapi-mesa通过降级软件包

    sudo apt-get install libglapi-mesa=10.5.2-0ubuntu1

您已经从 PAA 安装了版本 10.6.0~git20150423.125574d1-0ubuntu0ricotz~utopic，该版本不再存在于您的系统中，或者通过手动dpkg -i或其他工具安装。

但你的系统已经很糟糕了。

工作正在进行中...

在这种情况下，没有固定的步骤顺序。你必须自己决定并采取行动。我只能给你建议。

目前我们只有Synaptic Package Manager，因此使用它：

• 禁用不必要的 PPA 和其他存储库。您可以稍后重新添加它们。

  

  使用Reload

  

• 该类别中的所有软件包Installed (local or obsolete)都应删除或降级

  首先尝试降级。如果不可能，请取出包装。一步一步地进行，而不是一次性完成。每次删除后，检查类别Installed (auto removable)并删除包。请记住，可以重新安装软件包，但不应删除内核；）

  有时需要重新启动 Synaptic。但这个断言来自我的经验，并不一定是真的。

  

• 删除可以重新安装的软件包

以下是聊天中的一些要点

• 重新启动系统之前检查

  • 你的桌面还安装着吗？

    apt-cache policy unity
    

  • 你的网络管理器安装了吗？

    apt-cache policy network-manager
    

  • 你的显卡安装了吗

    nvidia-settings --version
    

记住并提供有用的链接

• Unity 无法加载，没有启动器，没有出现 Dash

• 对于一台台式电脑来说，什么是好的备份策略？

• 如何找到包的反向依赖？
