更新到新的 bionic beaver Ubuntu 18.04 后，我遇到以下错误。
每当我尝试安装包时，都会出现以下错误：
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libunity-scopes1.0 : Depends: libnet-cpp2 (>= 1.1.0+15.04.20150305) but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
我试过了sudo apt --fix-broken install，但没用。它最终从我的系统中删除了很多包。以下是它的日志：

我尝试在这个论坛上寻找解决方案，但都无济于事。
