MonoDevelop cant create a new project

Hi there,
I’m trying to install monogame at my ubuntu 16.04.
First I couldn’t execute the basic mono game project.
nearly same like:

I did the suggested steps (but with ‘MonoDevelop’ instead of ‘Xamarin Studio’).

Now I even can’t create a project anymore. I get an error window if I’m trying to:

The project could not be created

Type 'MonoDevelop.Ide.GettingStarted.GettingStartedProjectExtension' not found in add-in 'MonoDevelop.Ide,6.2'

I am using flatpak version of MonoDevelop 6.1.4 with add-in MonoGame

Someone has any idea?

I’m having a similar problem, but it may not be related.

I’m on ubuntu 16.04.
Installed monodevelop 6.1.4 via flatpak.
Installed monogame 3.5 from
Addins working (, project created.

Getting error: TestProject.csproj could not import “$(MSBuildExtensionsPath)\MonoGame\v3.0\MonoGame.Content.Builder.targets” (TestProject)

I’ve been using monogame + vs for years on windows but finally made the switch to linux, so this is probably a newbie mistake. If you could explain the problem like I’m 5 years old, that would be great. Apologies if my problem is separate from theirs. Thanks!

Ye, exact this problem I got first.
