You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-image-extra-4.4.0-70-generic : Depends: linux-image-4.4.0-70-generic but it is not going to be installed
linux-image-extra-4.4.0-77-generic : Depends: linux-image-4.4.0-77-generic but it is not going to be installed
linux-image-generic : Depends: linux-image-4.4.0-77-generic but it is not going to be installed
Recommends: thermald but it is not going to be installed
mailutils : Depends: mailutils-common (= 1:2.99.99-1ubuntu2) but it is not going to be installed
Depends: default-mta or
mail-transport-agent
Depends: guile-2.0-libs but it is not going to be installed
Depends: libmailutils4 (>= 1:2.99.99) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
对于我来说，apt-get -f install这些都不起作用，从服务器收到相同的消息，我该怎么做才能解决这个问题？sudo apt-get update && timesudo apt-get dist-upgrade
答案1
在这些情况下，我通常使用aptitude，它具有更强大的依赖项解决引擎。命令完全相同，sudo aptitude install mailutils。它将开始向您提出各种解决方案，要求您确认或转到下一个解决方案。选择时要小心，因为有时它会删除一些对系统至关重要的依赖项（我遇到过这种情况，因为我没有仔细阅读建议的解决方案将删除重要的软件包）
