wireless - Can't install drivers for my Broadcom 43142

I'm a newbie when it cames to linux and after some research I've decided that Mint was the best option but I'm having many problems trying to install the drivers for my wireless card that is a Broadcom 43142.

I was searching on the internet for several days trying to fix my problem, but with no change, it still doesn't work...

On the terminal I wrote this just to confirm the Wireless Card:

lspci -vnn | grep 14e4

03:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)

With that info I've searched for a Broadcom Wireless Table and I've found that the package for my Broadcom is the bcmwl-kernel-source

But when I run the command: sudo apt-get install bcmwl-kernel-source I get:

Reading package lists... Done
Building dependency tree       
Reading state information... Done

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
  bcmwl-kernel-source : Depends: libc6-dev but it is not going to be installed
  libc6 : Breaks: locales (< 2.19)
  libc6:i386 : Breaks: locales (< 2.19)
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

And I've tried the command sudo apt-get -f install and more errors:

And again, nothing seems to work..

Can you please help me? I want to leave windows and stay only with Linux but I need to solve this first...
