Update from elementary OS Freya beta to stable Freya stable released toady and I have installed Freya beta 2. I want to update to stable so tried using `sudo apt-get dist-upgrade`but it shows nothing. Do I have to make a clean install or is a update possible?

First install the package that provides `add-apt-repository` if it's not already installed:


sudo apt-get install software-properties-common


Next, remove elementary beta PPA and replaced it with stable.


sudo add-apt-repository --remove ppa:elementary-os/daily
sudo add-apt-repository ppa:elementary-os/stable
sudo apt-get update


Now remove elementary beta packages


sudo apt-get remove elementary-os-prerelease


Update Linux kernel to 3.16 similar to stable release.


sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic


Upgrade the system and restart


sudo apt-get dist-upgrade
