Ubuntu – How to install Mono on a server

This is a somewhat vague answer, I know, but I hope it helps:

• Download the appropriate tarballs from http://ftp.novell.com/pub/mono/sources-stable/
• Follow the instructions for compiling at http://www.mono-project.com/Compiling_Mono_From_Tarball

The only dependencies listed on the latter page ARE NOT necessary for version 2.8, so you should (hopefully) have most everything you'll need already. But you're probably much more knowledgeable about this than I am, so hopefully the instructions there will give you all the info you need. Also, if you build from source, you shouldn't have any problems with the Ubuntu repo versions (unless you haven't completely uninstalled them already).

Good luck!

I presume you are trying to install that package using sudo dpkg -i package, well, that normally leads to package dependency problems so normally I suggest the use of gdebi. If you have any problematic package remove it. You can check using sudo apt-get check. Now down to business:

sudo apt-get install gdebi-core

With that we have ready gdebi. Now if you use a 64-bit system you may like to install the 64-bit package, likewise with 32-bits.

Now here comes the funny stuff...

sudo gdebi graphviz_2.37.20140208.0545-1\~saucy_amd64.deb

This package is uninstallable
Dependency is not satisfiable: libgd2-noxpm (>= 2.0.36~rc1~dfsg)|libgd2-xpm (>= 2.0.36~rc1~dfsg)

And here is where you stop. The reason is that the stable package depends on package that were dropped of Debian, ergo Ubuntu 13.10:

libgd2 (2.0.36~rc1~dfsg-6.1) unstable; urgency=low

  * Non-maintainer upload.
  * Support multi-arch: (closes: #652496)
    - Mark libgd2-xpm, libgd2-noxpm, libgd2-xpm-dev and libgd2-noxpm-dev
      as same.
    - Adjust d-shlibs and dh-buildinfo build-dependency.
  * Drop .la files.

Those are dependencies of graphviz so they should change them to libgd2-xpm-dev and libgd2-noxpm-dev respectively. If that's the case, you should download the latest build instead 2.38 or later, which includes the correct dependencies.
