Dubbed Xenial Xerus, Ubuntu 16.04 LTS was released on April 21, 2016, with the Unity desktop environment, and it’s supported until April 2021. The Ubuntu 16.04.5 LTS point release is the last in the series and like all the previous point releases, it represents an up-to-date installation medium for those who want to install a fresh Ubuntu 16.04 LTS system. There won’t be further point releases released for Ubuntu 16.04 LTS (Xenial Xerus), so if you want to deploy the operating system on a new computer one year from today, you’ll have to download the Ubuntu 16.04.5 LTS images and then update the installation by downloading all the security updates released during the respective period.
