The latest version of Ubuntu is 24.04 LTS

The latest version of Ubuntu as of November 2024 is Ubuntu 24.04 LTS, also known as “Noble Numbat.” This Long Term Support (LTS) release offers improvements in performance, usability, and system stability, and it will receive updates and support for up to 12 years for Ubuntu Pro users.

Key Features and Updates:

1. GNOME 46: Enhancements to the desktop environment include improved notifications, reorganized system settings, and a refined Nautilus file manager.
2. Updated App Center: A more intuitive and faster interface, though there is a continued emphasis on Snap packages over traditional .deb files.
3. Accessibility and Installation: Simplified installation process, better accessibility features, and an option for minimal installations.
4. System Improvements: Includes Linux Kernel 6.8, improved fractional scaling, and TPM-backed full-disk encryption for enhanced security.
5. Software Updates: A new GUI firmware updater and refinements to existing tools like Netplan for network configuration.

Considerations:

While Ubuntu 24.04 brings significant upgrades, it emphasizes Snap over .deb, which might not suit all workflows. Additionally, it’s best to back up your data before upgrading due to potential compatibility issues with certain setups.

Upgrading to Ubuntu 24.04 LTS is a straightforward process, especially if you’re running a supported previous version, such as Ubuntu 22.04 LTS or 23.10. Here’s a step-by-step guide:

Before You Start

1. Backup Your Data: Ensure all important files are backed up to avoid data loss.
2. Check for Updates: Ensure your current system is fully updated. sudo apt update && sudo apt upgrade -y && sudo apt autoremove
