我尝试通过 Synaptic 更新我的软件包，但我有一段时间没有更新了，所以花了一段时间。更新时我收到一个错误，说我破坏了软件包，需要使用 来修复它apt-get install -f，似乎是因为 Synaptic 在更新过程中变得没有响应/崩溃了。我无法关闭 Synaptic，因此我开始进行故障排除，并在某个时候单击重新启动以查看会遇到什么样的错误，但它实际上重新启动了，但是 xserver 无法启动，因此没有桌面环境。我尝试apt-get install -f通过 tty2 再次运行，但它给了我某种错误并告诉我执行命令sudo dpkg --configure -a。经过这个过程，我的桌面可以使用了，看起来也没有错误，但没有我的主题。
这次我apt-get install -f成功运行，然后完成了更新，全部在 tty2 中，因为我无法在桌面上打开终端窗口。更新完成后，我重新启动到桌面，如下所示。登录屏幕看起来不是这样的，只有桌面环境看起来像这样，而且这种效果也会影响桌面上的所有应用程序。除此之外，桌面环境 100% 可用。我还查看了 .xsession-errors，错误似乎记录在这里，但我不知道如何处理此信息。
