Hi guys, I'm kinda new to Ubuntu and I noticed that my battery has been draining really fast, I did some checkinh and I understood that bumblebee should help that, so I installed bumblebee and also tried installing primus (through the terminal) and ever since then the software manager has a problem installing packaged and says it should be repaired or the package needs to be removed.

I have an Asus550jv

I get this log when I try to repair:

I've already tried :
sudo apt-get install -f
sudo apt-get clean
sudo apt-get autoclean
sudo apt-get update
sudo apt-get dist upgrade
sudo apt-get autoremove
and when i try "sudo dpkg --configure -a" I get :

dpkg: dependency problems prevent configuration of primus:

I really don't know what else left to do so, please any help would be very appreciated
