Package system broken? Libqtcore4? Kollision? Software Center? What?

[CommanderLiamTHX]

I recently installed Xubuntu on my Acer C720, and I tried downloading a game called "Kollision" from the Software Center. It freaked out and started giving me a popup every two seconds if the Software Center was open that said "New software can't be installed, because there is a problem with the software currently installed. Do you want to repair this problem now?" I clicked repair, it asked my password, then it briefly said "Package Operation Failed" and pulled up another popup asking me t repair my software. I can't install ANYTHING from the Software Center OR Terminal, and I have not yet installed Synaptic. Even if "Install Synaptic" is the answer and I can somehow do it, I would still want to install from the terminal.

What happens when you run

sudo apt-get install -f

from the terminal?
EDIT: Also might want to run

sudo apt-get remove kollision

and

sudo apt-get autoremove --purge

and

sudo apt-get autoclean

Thanks for the reply. The method didn't work for me, but I figured it out on another website. Turns out it was something wrong with the iso on Distroshare, someone else had the same problem and it got solved in the comments.
