I am using Ubuntu 13.10 (with Gnome 3.10.1) and MonoDevelop

Before switching to GDM and Gnome 3 MonoDevelop worked just fine, but after switching I get this popup: "Could not connect to debugger" (as the picture shows, first the "Waiting.." popup pops up, then the could not connect (all this happens instantly)).

I am aware you can use the internal console (Project -> Options -> General) but it does not do it for me. I want the Gnome-terminal as I'm used to.

Does anyone know a fix to this? (Yes, I've tried reinstalling (including apt-get purge and removing the settings in ~/home)

This is due to a recent gnome-terminal change. Recent gnome-terminal no longer accepts the --disable-factory argument.

Install the xterm package, then in a gnome-terminal session do the following:

$ monodevelop

This will cause monodevelop to use xterm as its external terminal and all should be well.

this little trick , works on my debian 8 (Cinnamon)

  1. Go to Solution Options via Project > ProjectName Options
  2. Under Run > General Section disable the Run on external Console for both Debug and Release Configuration

now it should work for you.

What is happening here that Mono is trying to open mcs to execute the console program. But since the mcs is not installed in the system, it keeps giving that error message. You just need to install mcs and that's all.

Open up the terminal and type this command: sudo apt-get install mono-mcs

This will probably solve the issue.
