To install the Cinnamon 3.0 desktop environment in the Ubuntu 16.04 LTS or Ubuntu 15.10 (Wily Werewolf) operating system – though the latter will be supported by Canonical with software updates and security fixes for a couple of months, until July 2016 – you’ll need to add the following PPA (Personal Package Archive).
Once you’ve executed all the above-mentioned commands in the Terminal app, one by one hitting the Enter key after each one, and everything is successfully installed, you can enter the Cinnamon session. You can do that by logging out and choosing “Cinnamon” from the login screen, by clicking on the small Ubuntu logo located on the right side of the username.
That’s it, you can now enjoy the Cinnamon 3.0 desktop environment on your Ubuntu 16.04 LTS or Ubuntu 15.10 operating system. However, if you decide that Cinnamon is not for you, you’ll have to execute the following commands in the Terminal app to remove the Cinnamon 3.0 installation from your Ubuntu OS.
sudo apt-get install ppa-purge
sudo ppa-purge ppa:embrosyn/cinnamon
