问题
I'm trying to install Monodevelop from http://www.mono-project.com/docs/getting-started/install/linux/#debian-ubuntu-and-derivatives.
I'm using a virtual Box VM via Vagrant with an Ubuntu Precise 64 Guest OS
I have done this steps :
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
At this point, all seems OK. But when I want to install the first package "mono-devel" by typing
sudo apt-get install mono-devel
I have the following error message
vagrant@precise64:~$ sudo apt-get install mono-devel
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

I have also tried doing a "sudo apt-get upgrade" without any success.
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 ?
How to solve the problem ? Is there a mistake somewhere ?
As SushiHangover advises me in the answer below, I have also tried to install libgdiplus but there is also an error message :
vagrant@precise64:~$ sudo apt-get install libgdiplus

The following information may help to resolve the situation:
The following packages have unmet dependencies:
libgdiplus : Depends: libfontconfig1 (>= 2.9.0) but 2.8.0-3ubuntu9.1 is to be installed
Depends: libtiff5 (> 4.0.0-1~) but it is not installable
E: Unable to correct problems, you have held broken packages.
After manually installed libtiff5 package :
vagrant@precise64:/vagrant$ sudo apt-get install libgdiplus

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libgdiplus : Depends: libcairo2 (>= 1.4) but it is not going to be installed
Depends: libexif12 but it is not going to be installed

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
回答1:
Try running this:
sudo apt-get install libgdiplus
If it results in:
~~~
libgdiplus : Depends: libjpeg62-turbo (>= 1.3.1) but it is not installable
~~~
Then you need to get the older libjpeg62 package:
wget http://ftp.br.debian.org/debian/pool/main/libj/libjpeg6b/libjpeg62_6b2-2_amd64.deb
sudo dpkg --install --recursive --auto-deconfigure libjpeg62_6b2-2_amd64.deb
Now you can:
sudo apt-get install mono-devel
sudo apt-get install monodevelop
回答2:
New mono versions need libtiff5 package version >=4.0, and Ubuntu 12.x hasn't this package. But this package version depends on other new packages or existing packages with newer versions...
There is a working solution (on amd64 platform):
