When I try to run an example application it says I am missing a file that is found in OpenGL. I found information online and tried to install OpenGL with the following command:
sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev

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

The following information may help to resolve the situation:
The following packages have unmet dependencies.
freeglut3-dev : Depends: libgl1-mesa-dev but it is not going to be installed or
libgl-dev
Depends: libxt-dev but it is not going to be installed
Depends: libxext-dev but it is not going to be installed
libglu1-mesa-dev : Depends: libglu1-mesa (= 8.0.2-0ubuntu3) but 8.0.4-0ubuntu0.4 is to be installed

How do I fix this ?
