apt - Can't install AMD drivers ubuntu 14.04

So when i try to install AMD driver from their website it always give me that error:

• Please install the required pre-requisites before proceeding with AMD
  Catalyst installation. Please check file
  usr/share/ati/fglrx-install.log for more details.

I already have installed all stuff from log, but there is one thing that I don't know how to fix :

(log)

• NOTE: If your system has logged the missing packages required for
  installation, install them in the order as per the log file to
  resolve package-dependency issues. fglrx installation requires that
  the system has kernel headers.
  /lib/modules/4.2.0-41-generic/build/include/linux/version.h cannot be
  found on this system. Install kernel headers using the command
  apt-get install linux-headers-4.2.0-41-generic.

The package name is actually linux-headers-generic-lts-wily that you want to install. This should pull in the headers and keep them updated with kernel updates you install.
