我最近从 dpkg 信息中删除了所有 python 文件来解决这个问题，但这不起作用，甚至损坏了。然后安装 ubuntu-desktop 后，再次面临同样的问题。

答案1
简单来说，如果你删除了 dpkg 应该处理的文件，它就会报错。通常，您不应删除本应由包管理器处理的文件。
重新安装软件包，然后使用 apt、dpkg 或您最喜欢的前端正确卸载它们，一切都会好起来的。
最坏的情况是彻底重新安装系统。是的，您可以在重新安装时保留用户数据。
请注意，如果您由于依赖关系而无法卸载某些内容，则意味着您可能需要它并且不应该卸载它。以后不要手动卸载东西。您最应该做的就是添加一些缺失的链接或编辑一些配置文件。
