After installing Ubuntu 16.04 LTS, I found that gcc 5.3 installed by default but I don't receive any updates to gcc. I opened up GCC website and I found the new release 6.1. How do I update?

Output of gcc --version:

gcc (Ubuntu 5.3.1-14ubuntu2.1) 5.3.1 20160413

You can install GCC 6 by adding the ubuntu-toolchain-r/test PPA. To do so, run the following commands:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

sudo apt update

sudo apt install gcc-6

You can verify that gcc-6 is installed by running gcc-6 --version and the output should say gcc-6 (Ubuntu 6.1.1-2ubuntu12~16.04) 6.1.1 20160510.

As suggested by Mohamed Slama, if you want to further change the default GCC and G++ to the latest versions, install g++-6 with

sudo apt install g++-6

and then run

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 60 --slave /usr/bin/g++ g++ /usr/bin/g++-6
