我不确定是什么导致了此错误，但是这就是整个错误的意思，这也是一个通知，它阻止我使用Update Manager更新任何软件-请提供帮助或告诉我如何确定修复它。
Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade.
Please report this bug against the 'update-manager' package and include the following error message:
'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'

这篇文章可以解决您的问题。总而言之，
/var/log/dist-upgrade/apt.log在文本编辑器中打开日志文件。sudo apt-get remove <package>注意：在较新的版本中，日志位于/var/log/apt/term.log。
cat: /var/log/dist-upgrade/apt.log: No such file or directory
该错误可能是由于软件包安装不完整引起的。
您有两种选择，1）修复损坏的安装，或2）回滚（或删除）损坏的安装。
由于上面没有提到，因此要回滚并删除损坏的安装，请退出突触（如果您仍在其中），然后在终端中输入以下命令：
sudo apt-get update # Make sure your package list is up to date
sudo apt-get autoremove # Removes "no longer required" packages
然后，确认损坏的软件包已消失，返回到突触并选择，Edit|。Fix broken packages而且应该没有破损的包装。
请注意，这不能解决损坏的安装问题，它仅允许您与其他安装或拆卸过程类似地再次突触。
发生的事情是，您开始安装软件包，然后进行部分安装，在安装了某些依赖项之后，出现了问题，留下了未使用的依赖软件包，并且安装不完整。
从16.04升级到18.04并在中间断电时出现此错误。
这就是错误的样子，而apt-get install -f不能修复它。

E: Unmet dependencies. Try using -f.
我还尝试sudo apt-get remove了/var/log/dist-upgrade/apt.log中的软件包，但是也没有用。
这个为我工作
dpkg -l | grep ^iU | awk '{print $2}' | xargs sudo dpkg --purge
它删除了破损的包裹，然后我跑了
apt install -f
它下载并安装了软件包。
