unmet dependencies while installing Ros on Ubuntu [closed]

edit

Hello,

I'm using Ubuntu 13.04 (Raring) x64 with a virtual machine

I run:

  sudo apt-get install ros-hydro-desktop-full  

I get:

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:
 
The following packages have unmet dependencies:
 ros-hydro-desktop-full : Depends: ros-hydro-desktop but it is not going to be installed
                          Depends: ros-hydro-mobile but it is not going to be installed
                          Depends: ros-hydro-perception but it is not going to be installed
                          Depends: ros-hydro-simulators but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
 

I have also checked other solutions and many of them suggested using aptitude, still I couldn't use aptitude since I had errors while installing its package.

If you need more details let me know.

Help me !

Thanks :)

[UPDATE]

It's just that ROS Hydro didn't work out with ubuntu 13.04 due to its instability I guess. I recommend you guys, if you have this problem, to switch to a more stable ubuntu distribution (12.04 LTS worked just fine with me)

Thanks :)
