我使用 kubuntu ppa 在 Ubuntu unity 16.04（标准版本）上安装 kubuntu-desktop。这导致软件包损坏。正如其他人指出的那样这里和这里，他们无论如何都想出了如何安装 kubuntu-deskop，但是，我不再倾向于使用 plasma。所以我正在卸载它。我只是在软件和更新 > 其他软件中取消选中 kubuntu ppa/backports/Ubuntu Xenial。然后sudo apt-get remove kubuntu-desktop。我后来意识到，这不是摆脱与我的 unity DE 冲突的 kubuntu 系统的最佳方法。无论如何，当我尝试安装 unity tweak 工具时，我吃尽了苦头才学到这一点。
所以基本上我意识到我没有以良好的方式摆脱 ppa 安装的软件，导致软件包损坏。现在我在安装其他软件包时没有注意到这一点。只有在处理 qt、unity 等时我才会遇到这个问题。我尝试安装所有 unity 的东西，希望这会删除所有与 kubuntu 相关的软件包。
sudo apt-get install unity-*
我收到此错误：-

在其他地方，他们建议清理、自动清理、升级、分布式升级、自动删除等。尝试了所有方法，但没有结果。Unity 似乎存在冲突。有趣的是，当我尝试时：-
sudo apt-get install python3-pyqt5
它遇到错误：-

使用aptitudealso 也是徒劳的。它只是说我无法解决您的问题，却什么也没做。有人能帮我弄清楚如何正确删除 kubuntu 和其他软件并正确重新安装 unity 吗？
