原因基本如下：
1，你添加了新的源，但这个源不适合这个系统，有版本要求。有很多把Ubuntu 22.04的源添加到了Ubuntu 20.04上。当你执行安装的时候，默认会把新的包装到系统，但系统的依赖包是旧的，所以提示这个错误。
很多网上的方案，基本都没说到这个原因。导致很多人可能卸载旧的依赖，把整个系统搞崩溃了。
2，没有更新安装包信息到系统环境里去。一般是通过编译安装产生的，那怕是安装了，也提示版本更新。这个就比较麻烦，需要你把编译安装的路径，更新到系统的Path里面去。
3，不要轻易用 apt autoremove 相关的命令。这个命令明确意思是告诉你 自动删除一些不用的包。但实际上如果你不了解整个包的关联逻辑，很容易造成某些服务无法启动，甚至系统的奔溃的情况。也会造成某个包因为依赖无法更新。
