title: Monodevelop - Try to install on linux Precise 64 (Ubuntu 12.04 LTS)
body: <p>I'm trying to install Monodevelop from <a href="http://www.mono-project.com/docs/getting-started/install/linux/#debian-ubuntu-and-derivatives" rel="nofollow">http://www.mono-project.com/docs/getting-started/install/linux/#debian-ubuntu-and-derivatives</a>.</p>
  
  <p>I'm using a virtual Box VM via Vagrant with an Ubuntu Precise 64 Guest OS</p>
  
  <p>I have done this steps :</p>
  
  <pre><code>sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
  echo "deb http://download.mono-project.com/repo/debian wheezy main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list
  sudo apt-get update
  
  echo "deb http://download.mono-project.com/repo/debian wheezy-libtiff-compat main" | sudo tee -a /etc/apt/sources.list.d/mono-xamarin.list
  </code></pre>
  
  <p>At this point, all seems OK.
  But when I want to install the first package "mono-devel" by typing </p>
  
  <pre><code>sudo apt-get install mono-devel
  </code></pre>
  
  <p>I have the following error message</p>
  
  <pre><code>vagrant@precise64:~$ sudo apt-get install mono-devel

  <p>I have also tried doing a "sudo apt-get upgrade" without any success.</p>
  
  <p>I thought that apt could also download and install all package dependencies. Why the libraries files mentioned in the error message can't be loaded ?</p>
  
  <p>How to solve the problem ? Is there a mistake somewhere ?</p>
  
  <p>As SushiHangover advises me in the answer below, I have also tried to install libgdiplus but there is also an error message :</p>
