Okay, I understand that there have been quite a few solutions to this problem. None of them have worked for me. To explain my conundrum I shall post the output of "sudo aptitude install wine1.7". EDIT: added result of sudo aptitude upgrade

Any further attempts to solve would return the same. I have tried most alternatives, including the software center and How do I resolve unmet dependencies after adding a PPA?. Help would be appreciated. Thank You. It is good to finally join the Ubuntu community.
P.S If needed, just ask for additional information.
