我的机器是 Ubuntu 16.04。
尝试升级 Mono 后，我面临依赖问题。

mono-complete is already the newest version (6.0.0.313-0xamarin3+ubuntu1604b1).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
mono-complete : Depends: ca-certificates-mono (= 6.0.0.313-0xamarin3+ubuntu1604b1) but 4.8.1.0-0xamarin1 is to be installed
mono-devel : Depends: ca-certificates-mono (= 6.0.0.313-0xamarin3+ubuntu1604b1) but 4.8.1.0-0xamarin1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

所以现在我没有 ca-certificates-mono，并且由于一些 Mono 问题我无法安装它。
答案1
Mono 项目 gitter 聊天室的好心人帮助我修复了这个错误。
mv /etc/mono/config.dpkg-new /etc/mono/config
进而
apt install ca-certificates-mono
解决了这个错误。
