Unable to install on Ubuntu 14.10

Question

Hi all. Im pretty newbie with linux so please bare with me. I just upgraded to Ubuntu 14.10, and due to some issues I have been happening (long story) removed Skype with the intention of simply just reinstalling it, but now I am unable to do so. I downloaded the Ubuntu 12.04 multiarch version (I assume that this means its compatible with various versions) and tried to open it via the software centre. I get an error in the software centre that says 'Cannot install 'libpulse0:i386'.
I ran a few other commands that I found on other threads that seemed to have similar problems, so so far I have run:
sudo apt-get clean && sudo apt-get update
sudo apt-get upgrade --fix-missing
And then tried the software centre again, but still the same problem.I tried installing the package manually through the terminal (sudo apt-get install libpulse0:i386) and got this result:
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
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
 libpulse0:i386 : Depends: libsndfile1:i386 (>= 1.0.20) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Not really sure where to go from here :/ Any advice? Cheers!

UPDATE
I ran the repair broken packages option from the GRUB menu, and although it seemed to work for that package, I get the same issue now with another. The error reads:
Cannot install 'libqtwebkit4:i386'
Running that in a 'sudo apt-get install' command returns:
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
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
 libqtwebkit4:i386 : Depends: libgl1-mesa-glx:i386 but it is not going to be installed or
                              libgl1:i386
                     Depends: libqt4-opengl:i386 (>= 4:4.5.3) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
The end says there are broken packages. but I have already tried to use the repair option from the GRUB menu twice. Help?
