How to Check Ubuntu Version
It is good to know what version your Ubuntu is at any given time. But especially when working with servers or Linux systems, as they sometimes do not have a graphical interface for you to use.
Every two years, there is an LTS (Long Term Support) version published, with support for at least 5 years. The current LTS version is 20.04, released in April 2020. The Ubuntu version numbers refer to the year and month of release.
Every 6 months between the LTS versions, Ubuntu releases a provisional version. This may seem like a lot, but it makes the development more controlled. Versions are usually released in April and October, with the latest being 19.10.
On the other hand, all other versions that are not LTS have fairly short support and their goal is limited to testing new features and bug fixes.
Knowing your Ubuntu version will help you better understand what packages or applications you should be installing. So how do you check your Ubuntu version?
This article will teach you how to check your Ubuntu version information a few different ways, through the terminal and command line, and using the graphical interface on a desktop environment.
