How to install latest gcc on Ubuntu LTS (12.04, 14.04, 16.04)

These commands are based on a askubuntu answer http://askubuntu.com/a/581497 To install gcc-6 (gcc-6.1.1), I had to do more stuff as shown below. USE THOSE COMMANDS AT YOUR OWN RISK. I SHALL NOT BE RESPONSIBLE FOR ANYTHING. ABSOLUTELY NO WARRANTY.

If you are still reading let's carry on with the code.

sudo apt-get update &&
sudo apt-get install build-essential software-properties-common -y &&
sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y &&
sudo apt-get update &&
sudo apt-get install gcc-snapshot -y &&
sudo apt-get update &&
sudo apt-get install gcc-6 g++-6 -y &&
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 60 --slave /usr/bin/g++ g++ /usr/bin/g++-6 &&
sudo apt-get install gcc-4.8 g++-4.8 -y &&
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8;

When completed, you must change to the gcc you want to work with by default. Type in your terminal: sudo update-alternatives --config gcc

To verify if it worked. Just type in your terminal gcc -v

If everything went fine you should see gcc 6.1.1 by the time I am writing this gist

Happy coding!
