My machine is Ubuntu 16.04.
After I tried upgrade Mono I faced with dependency problem.
sudo apt-get install mono-complete
Building dependency tree
Reading state information... Done
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).
sudo apt-get -f install
