I am very new to Linux, so please forgive me if the answer to my question is obvious. Since I am running an ARM device and can’t install wine, I am trying to install Mono/Develop. The problem is, whenever I try to install any of the Mono packages, I am greeted with a huge block of “unmet dependencies.” For example:
(precise).....@localhost:~$ sudo apt-get install monodevelop
.

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 same thing happens when I try installing other packages such as mono-complete, but to a lesser extent.

I have tried following the instructions on http://www.howtogeek.com/howto/linux/installing-monodevelop-from-source-on-ubuntu/, on Mono-Project, and MonoDevelop, and running sudo apt-get update, but I keep getting that broken packages error.
Do I have to reinstall Ubuntu (which is fine with me, since I’m using Crouton), add all of those package names to sudo-apt-get install, or what?

I was facing similar issue. If you are happy to work with pre-release versions of mono then using monoxide PPA works. Run the following commands
sudo add-apt-repository ppa:directhex/monoxide sudo apt-get update sudo apt-get upgrade sudo apt-get install mono-complete
