Unable to fixed unmet dependencies

I m having a problem of unmet dependencies and broken packages while installing opennebula

i tried sudo apt-get -f install to remove all held broken packages but unable to fix.

i used
sudo aptitude install
sudo aptitude packagename

all packages installed but opennebula core( oned.conf) can’t be installed and if there maybe problem of configuration
My system configuration :

Hi @Ayushi,

you need a 64-bit system for the OpenNebula server. For 32-bit systems, only few architecture independent packages are released. What you see is a result of using mixed old OpenNebula 3.4.x packages from the Ubuntu, and those few architecture independent latest packages from the OpenNebula.org.
