1. What Is Ubuntu LTS? Importance and Core Overview
Ubuntu is one of the most widely used Linux distributions among engineers and IT users around the world. Among its releases, the most popular is the “LTS” version (Long Term Support). This section explains the key features of the LTS edition and why it is essential for both general users and enterprise environments.
What Is Ubuntu LTS?
Ubuntu offers two release types: standard releases and LTS releases. Standard releases are published twice a year (April and October) and are supported for nine months. In contrast, LTS versions are released every two years in April of even-numbered years and provide long-term support. Each LTS release includes five years of security updates, and with paid support options, maintenance can be extended up to twelve years.
Why the LTS Edition Matters
The LTS edition stands out for its stability and long support cycle. For many companies and organizations, system reliability is critical. LTS minimizes bugs and security risks while offering predictable maintenance schedules, enabling system administrators and engineers to maintain stable long-term environments. The LTS version is also highly regarded by desktop users who prefer working in the same environment for extended periods.
Overview of the Latest Version
The latest LTS release, “Ubuntu 24.04 LTS,” was launched in April 2024. This version includes an updated Linux kernel that enhances performance and security. Improvements to the user interface and a redesigned installer further enhance the overall user experience.
Benefits for Enterprise and Individual Users
The LTS edition is ideal for enterprise users who need a stable server environment with long-term support. It provides a highly reliable infrastructure for mission-critical systems. For personal use, LTS is also suitable for users who want to avoid frequent updates or need a stable development environment. Because Ubuntu is free to use, it is also a popular choice for startups and small businesses looking to minimize IT costs.
For these reasons, Ubuntu LTS remains the preferred choice for users who prioritize stability and long-term maintenance. In the next chapter, we explore the new features and improvements introduced in Ubuntu 24.04 LTS.
2. New Features and Improvements in Ubuntu 24.04 LTS
Ubuntu 24.04 LTS, released in April 2024, focuses on stability, performance, and usability. This section highlights the major improvements and new features introduced in this release.
New Linux Kernel and Performance Enhancements
Ubuntu 24.04 LTS integrates the latest Linux kernel, offering better performance compared to the previous LTS version (22.04). The updated kernel improves hardware compatibility, enabling support for the latest devices and peripherals. It also enhances processing speed in multitasking scenarios, making the release suitable for both server operations and desktop environments.
Improved User Interface and New Installer
Ubuntu 24.04 LTS introduces an updated user interface for more intuitive operation. A redesigned installer simplifies the installation process, making it easier for beginners to set up the system. The unified visual design improves consistency across the user interface, boosting readability and usability.
Enhanced Security Features
Security has been significantly strengthened in Ubuntu 24.04 LTS. New enterprise-grade data protection features improve system integrity. Automatic security updates ensure users always run the latest patches. The improved endpoint protection capabilities help safeguard against external attacks and prevent data leaks.
Optimized Snap Package Performance
Snap packages, widely adopted in Ubuntu, see significant performance improvements in 24.04 LTS. Application startup times are reduced, enhancing desktop responsiveness and enabling a smoother user experience.
Extended Enterprise Support: “Ubuntu Pro”
Ubuntu 24.04 LTS marks the full deployment of the paid “Ubuntu Pro” service. Ubuntu Pro extends support beyond the default five years, offering up to ten years of coverage. It provides advanced security options and long-term software maintenance, making it an appealing solution for enterprises operating mission-critical infrastructure.
3. LTS Support Lifecycle and Upgrade Guide
The Ubuntu Long Term Support (LTS) edition is ideal for users who require a stable system for extended periods. This section explains the LTS support cycle and provides a step-by-step guide to perform a smooth upgrade.
LTS Support Period and Key Characteristics
The standard support period for an LTS release is five years. During this period, users receive regular security updates and bug fixes, allowing long-term system operation in a stable environment. Additionally, a paid enterprise option called “Ubuntu Pro” extends support up to ten years, making the LTS release highly valuable for mission-critical systems and server environments.
A supplementary option called “Legacy Support” is also available. With this extension, users can add two additional years after the standard support period, enabling up to twelve years of maintenance. This extended support is particularly beneficial in enterprise environments where frequent system upgrades are impractical.
Upgrade Guide: From 22.04 LTS to 24.04 LTS
The upgrade process between LTS releases is designed to be simple. Ubuntu officially supports direct upgrades from one LTS version to the next, allowing installed software and system settings to be preserved. However, a few precautions are recommended before performing the upgrade.
Preparation Before Upgrading
- Create a Backup
Always back up important data and configuration files. Although Ubuntu upgrades are generally safe, backups ensure protection in case of unexpected issues. - Review the Release Notes
Before upgrading, review the release notes for Ubuntu 24.04 LTS to understand any known issues, limitations, and compatibility changes. - Update the Current System
Make sure your existing environment is fully updated, including all security patches and dependency packages.
Upgrade Steps
- Check for Software Updates
In Ubuntu Desktop, open “Software & Updates”, then configure the upgrade settings to enable LTS-version upgrades. - Command-Line Upgrade
For server environments or advanced control, use the following commands in the terminal:
sudo apt update && sudo apt upgrade -y
sudo do-release-upgrade -dOnce executed, Ubuntu attempts to upgrade to the latest LTS version. The process takes time, but simply follow the on-screen instructions to complete a seamless transition.
Choosing the Right Time to Upgrade
Whether to upgrade immediately depends on your environment. Users can continue using the current LTS release during its support period; for example, Ubuntu 22.04 LTS remains supported until 2027. If the latest features are not urgently needed, waiting is a valid option. System stability, feature requirements, and operational needs should guide the timing.
In virtual machine setups, taking a snapshot before upgrading provides a safe rollback option if issues occur.
4. Essential Post-Installation Settings and Optimization
After installing Ubuntu 24.04 LTS, performing initial configuration ensures the system runs efficiently and securely. This section introduces recommended settings for enhanced security and performance.
Strengthening Security Settings
Although Ubuntu LTS comes with robust security by default, applying the following configuration steps further increases protection.
- Enable the Firewall
Ubuntu includes “ufw” (Uncomplicated Firewall) as a built-in firewall tool. Enable it using:
sudo ufw enableThis restricts unnecessary network access and reduces potential attack vectors.
- Secure SSH Access
When using SSH for remote access, improve security by changing the default port (22) and enabling public key authentication instead of passwords:
sudo nano /etc/ssh/sshd_configAfter modifying the configuration, restart SSH:
sudo systemctl restart sshPerformance and System Optimization
To maximize system performance, adjust the following settings:
- Disable Unnecessary Services
Unused services consume memory and CPU resources. Check running services using:
sudo systemctl list-units --type=service --state=running- Optimize Swap Usage
Lowering swappiness improves system responsiveness:
sudo sysctl vm.swappiness=10- Enable Automatic Security Updates
Keep your system secure by enabling unattended upgrades:
sudo apt install unattended-upgrades
sudo dpkg-reconfigure unattended-upgrades
Recommended Applications for Beginners
Ubuntu offers a wide range of useful desktop applications:
- Ubuntu Software Center
A GUI-based tool for easily installing applications such as LibreOffice, GIMP, and VLC. - Snap Packages
Install the latest applications safely via Snap Store using:
sudo snap install <package-name>These configurations ensure Ubuntu 24.04 LTS is optimized for everyday use, development, and server deployment.
