To install the Cinnamon 3.0 desktop environment in the Ubuntu 16.04 LTS or Ubuntu 15.10/14.04 you’ll need to add the following PPA (Personal Package Archive).

sudo apt-add-repository ppa:embrosyn/cinnamon
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install cinnamon

Once you’ve executed all the above-mentioned commands in the Terminal application and everything is successfully installed, you can enter the Cinnamon session.

You can do that by logging out and choosing “Cinnamon” from the log in screen, by clicking on the small Ubuntu logo located on the right side of the user name.

To Remove Cinnamon 3.0 installation from your Ubuntu OS:
