When a new version of Ubuntu Linux is released, in addition to being able to reinstall it by clearing the previous Ubuntu system, you can use the Upgrade method to install a new version without deleting other software and personal information. It is possible to upgrade regular versions of Ubuntu to newer versions, but in the case of LTS versions, you can only upgrade to newer LTS versions without changing the settings. In this article, we are going to teach you How to Upgrade Ubuntu from 18.04 to 22.04 LTS.

How to Upgrade Ubuntu 18.04 to 22.04 LTS
If you have previously installed and used a version of Ubuntu on your computer and now want to use a newer version, we recommend that you upgrade instead of reinstalling. Before we go into the steps and conditions of the upgrade, remember that it is better to make copies and backups of all-important personal and business files so that there are no problems in case of inadvertent mistakes.
Introduction to Ubuntu 22.04
Ubuntu is one of the best options for enterprise use and serves as the technical basis for projects such as Linux Mint and Elementary OS. It should be noted that Ubuntu always releases two major versions a year, and as planned, Ubuntu 22.04 LTS is now available.
Ubuntu 22.04 is a long-term support (LTS) version, which means it will be maintained for fifty years with security fixes and selected updates. That way, if you do not want to deal with major updates on a regular basis, you can use the LTS version for years by installing the operating system and updating it until October 22, when the new version becomes available.
Ubuntu 22.04 is also the first version to run as a full desktop on the Raspberry Pi 4. This Ubuntu version also includes the OpenSSL v3 programming language, the RDP, the Linux 5.15 kernel and the Mesa 22 chart. Ubuntu 22.04 is available for AMD 64-bit and x86 PCs. WSL, Docker, and other services that provide image files on Ubuntu have released version 22.04 of this Linux distribution.
