You might want to run 'apt-get -f install' to correct these:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

没有一个apt-get -f install，sudo apt-get update && time，sudo apt-get dist-upgrade为我工作，从服务器获得相同的消息，我应该做什么来解决这个问题？

Answer 1

在这些情况下，我通常使用aptitude，它有一个功能强大得多的简洁解决器引擎。命令是完全相同的，sudo aptitude install mailutils。它将开始向您提出各种解决方案，要求您确认或进入下一个解决方案。小心选择，因为有时它会移除对系统至关重要的一些依赖项(这发生在我身上，因为我没有仔细阅读到建议的解决方案将删除重要的包)
