1. What is Ubuntu LTS? Importance and Basic Overview
Ubuntu is one of the most widely used Linux distributions among engineers and IT users worldwide. Among its versions, the “LTS” (Long Term Support) edition is particularly popular. In this section, we will explain the fundamental features of Ubuntu LTS and why it is important for both general users and enterprise environments.
What is Ubuntu LTS?
Ubuntu offers two types of releases: regular releases and LTS (Long Term Support) releases. Regular releases are published twice a year, in April and October, and each version is supported for nine months. In contrast, LTS releases are published every two years, in April of even-numbered years, and receive long-term support. LTS versions come with five years of continuous security updates, and with paid support, this period can be extended to up to 12 years.
Why Ubuntu LTS is Important and Preferred
One of the biggest differences between LTS and regular releases is its stability and long-term support. For many businesses and organizations, system stability is crucial. With fewer bugs and security vulnerabilities, along with a predictable maintenance cycle, LTS provides a reliable operating environment for system administrators and engineers. Additionally, LTS is a popular choice for desktop users who prefer a stable system for long-term use without frequent upgrades.
Overview of the Latest LTS Version
The latest LTS version, “Ubuntu 24.04 LTS,” was released in April 2024. This version includes the latest Linux kernel, offering enhanced performance and security. It also features improvements in user interface design and a new installer, making the overall user experience smoother.
Benefits for Enterprises and Individual Users
Ubuntu LTS is an ideal choice for enterprise users managing server environments. Its stability and long-term support make it possible to build highly reliable systems. For individual users, LTS is also beneficial, especially for those who want to avoid frequent updates or need a stable development environment. Additionally, since it is free to use, LTS is a cost-effective option for startups and small businesses.
Because of these advantages, Ubuntu LTS is particularly favored by users who prioritize stability and long-term support. In the next section, we will take a closer look at the new features and improvements introduced in Ubuntu 24.04 LTS.

With Ubuntu Pro, businesses can access advanced security options and extended software updates, making it a highly attractive option for enterprises that require long-term system stability.
3. LTS Version Support Period and Upgrade Guide
Ubuntu’s LTS (Long Term Support) versions are the ideal choice for users who need a stable system for extended periods. This section details the support periods for LTS versions and provides a step-by-step guide for upgrading to the latest LTS release.
LTS Support Periods and Features
Ubuntu LTS versions come with a standard five-year support period. During this period, regular security updates and bug fixes ensure a stable and secure system. For enterprise users, an optional paid service, “Ubuntu Pro,” extends support up to 10 years. This long-term support is especially beneficial for business-critical systems and server environments.
Additionally, a “Legacy Support” option is available, which allows users to extend support for an additional two years beyond the standard five-year period, bringing the maximum support duration to 12 years. This extended support is particularly valuable for enterprise environments and systems that cannot be frequently updated.
Upgrade Guide: From Ubuntu 22.04 LTS to 24.04 LTS
Ubuntu provides a straightforward upgrade process for moving from one LTS version to the next while preserving installed software and settings. However, before upgrading, there are several key considerations.
Pre-Upgrade Preparations
