Ubuntu 24.04.5 LTS release patches security bugs across ten flavors

Canonical has released Ubuntu 24.04.5 LTS, bringing high-severity bug fixes and security updates directly to new installation media for the Noble Numbat release. The point release updates desktop, server, and nine other flavors like Kubuntu and Xubuntu, reducing post-installation update batches for fresh setups.

Noble Numbat Point Release Bundles Security Fixes

Canonical shipped the updated installation media to cut down the batch of updates that typically follow a fresh setup.

Reimaging with the new media simply saves a round of post-install downloads. Waiting, on the other hand, costs nothing beyond the packages a machine fetches during its next regular update cycle. Existing Ubuntu 22.04 LTS users do not need to take manual action, as the Update Manager handles the transition.

Desktop, Server, and Nine Flavors Covered

The point release extends well beyond the standard desktop and server editions. These include Kubuntu, Xubuntu, Ubuntu MATE, Ubuntu Studio, and Edubuntu. Each participating flavor carries its own release notes detailing flavor-specific changes.

Canonical built this update around stability fixes and security corrections, addressing the core priorities expected from a long-term support release intended to run unattended for years. However, the release notes omit specific CVEs and bug IDs. Administrators requiring explicit patch confirmations for compliance must consult the linked flavor release notes directly.

Support Timelines and Maintenance Windows

Understanding support timelines is critical for long-term deployment planning. Meanwhile, the other nine flavors receive three years of support.

Organizations tracking end-of-life dates for compliance or infrastructure planning must anchor their countdowns to the initial 24.04 launch. Systems requiring security coverage beyond those standard windows can incorporate Expanded Security Maintenance on top of their existing deployments. The support clock keeps counting regardless of whether an administrator reimages immediately or relies on automatic background updates.

Free Upgrade Path via Update Manager

Upgrading to the latest point release remains straightforward for current users. Canonical confirms that this upgrade route stays entirely free, consistent with all standard Ubuntu version upgrades.
