Released last year on April 13, Ubuntu 17.04 (Zesty Zapus) was the last version of the popular operating system to ship with the Unity 7 desktop environment by default. It was powered by the Linux 4.10 kernel series, Mesa 17.0 graphics stack, and X.Org Server 1.19 display server. Being supported for only nine months, Ubuntu 17.04 reached end of life today, January 13, 2018, and it will no longer receive any software updates or security patches. Therefore, those who still use the operating system are urged to update their systems to the latest Ubuntu 17.10 (Artful Aardvark) release as soon as possible.
