I just did a fresh install of Ubuntu 14.04 64-bit, and it seems that most major packages I attempt to install (among them being Skype, Steam/Steam-Launcher, WINE, etc.), give an "unmet dependencies" error and refuse to install.

I have looked at several other questions of a similar description (many duplicates) but none of the solutions worked and I have not yet found someone with this specific issue.

Installing Skype:

stere0123@stere0123-THINKPAD-U14:~$ sudo apt-get install skype

Reading package lists... Done

Building dependency tree       

Reading state information... Done

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:

 skype : Depends: skype-bin

E: Unable to correct problems, you have held broken packages.

stere0123@stere0123-THINKPAD-U14:~$ 

I get similar errors with some other packages I've tried as well.
Any help would be greatly appreciated as this problem is currently crippling this system!
