unmet dependencies problem ros indigo ubuntu 32 bits trusty

edit

HI! How are you doing?

I'm following the instructions( http://wiki.ros.org/indigo/Installati... ) to install ROS Indigo in my 32bit PC, with Ubuntu:

Distributor ID: Ubuntu
Description:    Ubuntu 14.04.5 LTS
Release:    14.04
Codename:   trusty

and finally i'm getting this error:

jrr10@jrr10:~$ sudo apt-get install ros-indigo-desktop-full

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:
 ros-indigo-desktop-full : Depends: ros-indigo-desktop but it is not going to be installed
                           Depends: ros-indigo-perception but it is not going to be installed
                           Depends: ros-indigo-simulators but it is not going to be installed
 unity-control-center : Depends: libcheese-gtk23 (>= 3.4.0) but it is not going to be installed
                        Depends: libcheese7 (>= 3.0.1) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

I've read a lot of posts and questions but i couldn't achieve my goal.

I would appreciate if you could help me out to solve this. Thanks in advance.
