我正在运行 ubuntu 18.04。当我尝试使用 synaptic 包管理器进行更新时，我收到以下消息
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
于是我上网寻找解决方案，并尝试了很多方法。以下是我目前收集到的信息。所有这些都是我在阅读其他帖子后尝试的方法，所以我不确定它们是否相关，但我想尽可能多地提供信息。
当我这样做时，sudo apt-get update它工作正常。当我这样做时，sudo apt-get upgrade我收到以下消息。

因此，我认为我有未满足的依赖关系，但我不知道如何修复它，或者这是否是问题所在。如果有人能帮助我，我将不胜感激。
更新
不知道发生了什么，但过了一会儿，一切又恢复正常了。Synaptic 又开始工作了，但是文件管理器上出现了一个新位置，名为 x-nautilus-desktop:///。当我点击它时，它说无法显示。很奇怪。

尝试这个：
sudo dpkg --configure -a
然后通过运行此命令删除输出中出现的包
sudo dpkg --remove package-name
