What is Ubuntu 18.04 LTS?
Ubuntu 18.04 LTS is a Long Term Support version of the free and open source Linux distribution Ubuntu. The operating system was released on 26th April 2018 and has a 3 year continued support cycle after the initial release. The Ubuntu LTS versions are used by people who want to run a secure desktop or server with continued support throughout its lifespan.
