OS: Linux Mint 18.2 Cinnamon 64-bit.

App: MonoDevelop, current version 7.1, i.e. not the old packaged one in the official repository.

I've had it installed badly using flatpak. Meaning the MonoDevelop would not launch at all, for a long time. Now, I wish to start using it again.

This is the only application using flatpak as an installation platform on my computer, so I decided to completely purge and delete remnants of both flatpak, and MonoDevelop.

After normal un-installation, I deleted everything else using locate.

Now what was my new procedure:

1. 
   

   Re-add the flatpak repository and re-install flatpak:

   
   
   

   $ sudo add-apt-repository ppa:alexlarsson/flatpak
   $ sudo apt-get update
   $ sudo apt-get install flatpak
   

   
   


2. 
   

   Checking flatpak's version is above 0.8:

   
   
   

   $ flatpak --version
   
   Flatpak 0.10.0
   

   
   


3. 
   

   Following the abnormally short official installation instructions:

   
   
   

   $ flatpak install --user --from https://download.mono-project.com/repo/monodevelop.flatpakref
   
   This application depends on runtimes from:
    https://sdk.gnome.org/repo/

No error, great. But...

This is what I get as an error when running it as normal user with:

$ flatpak run com.xamarin.MonoDevelop

As you can see, it asks me if I want to continue without extensions, so I can theoretically say Yes and it will be running without them.

I don't really know what to do with it.

Question: Did I do anything wrong? Or is there anything missing and I could install it?
