Note: Before doing the upgrade, you can use the systemback program to create a bootable ISO image from your current OS. Ubuntu 20.10 will reach end of life this July, so I recommend 20.10 users upgrade to Ubuntu 21.04 ASAP. But if you are the other way around, you can follow this tutorial to upgrade from Ubuntu 20.04 to 21.04. If you prefer stability over bleeding edge, then stick with Ubuntu 20.04. Ubuntu 21.04 is a non-LTS release, which means it will be supported for 9 months only, until January 2022.

Ubuntu 20.04 is a long-term support (LTS) release, which will be supported for 5 years. Usually, you use the graphical update manager to upgrade Ubuntu desktop and use the command line to upgrade Ubuntu server, but the command-line method works for desktops too. The first method uses the graphical update manager and the second method uses command line. This tutorial is going to you 2 ways to upgrade Ubuntu 20.04/Ubuntu 20.10 to 21.04.

Ubuntu 21.04, codenamed Hirsute Hippo, is released on April 22, 2021.
