Canonical has released Ubuntu 24.04.5 LTS, the latest maintenance update for the “Noble Numbat” long-term support line. The refresh brings an updated installer image loaded with security patches, bug fixes, and a hardware enablement stack anchored on the Linux 7.0 kernel. Designed for organizations running Ubuntu at scale, the point release emphasizes stability and security without forcing users into a disruptive version bump.
What’s New: Hardware, Toolchains & Support Lifecycle
The standout enhancement in this release is the shift of the Hardware Enablement (HWE) kernel stack to Linux 7.0, borrowed from the newer Ubuntu 26.04 LTS “Resolute Raccoon.” Alongside it comes Mesa 26.2 to improve graphics compatibility. Users preferring legacy stability can stick with the original General Availability (GA) kernel, which remains at the Linux 6.8 series—the version that shipped with Ubuntu 24.04.0.
Developer tooling also gets a major bump: GCC 14, glibc 2.39, Rust 1.75, and Python 3.12 are now default components in the installation media. These updates mean fresh installs are better equipped for modern workloads straight out of the box. Livepatch support now covers the 7.0 HWE kernel stack on x86-64, making it possible to apply high-severity kernel fixes without rebooting.
Maintenance, Support & Upgrade Paths
Ubuntu 24.04.5 LTS integrates a large batch of security corrections and serious bug fixes into the software installer, so new deployments won’t need to immediately pull down huge updates. Existing Ubuntu 24.04 systems that are regularly updated will receive the same fixes through standard channels, without needing to reinstall.
Support timelines remain consistent: standard security support for Ubuntu Desktop, Server, Cloud, and Core will continue through May 2029, while community flavors inherit a three-year window from the original release. For organizations needing extended protection, Canonical’s Extended Security Maintenance (ESM) through Ubuntu Pro stretches usable coverage toward a full decade.
The nine official Ubuntu flavors—including Kubuntu, Xubuntu, Ubuntu MATE, Lubuntu, Ubuntu Kylin, Ubuntu Studio, Edubuntu, Ubuntu Cinnamon, Ubuntu Budgie, and Ubuntu Unity—have also been updated to version 24.04.5, each adapting flavor-specific fixes and updates.
Upgrade paths are straightforward: users of Ubuntu 22.04 LTS can move to 24.04.5 via the Update Manager at no cost. For administrators, switching to the 7.0 HWE kernel offers leading-edge hardware support; those prioritizing long-term stability can remain on the established 6.8 GA track.
What this means: Ubuntu 24.04.5 LTS isn’t about flashy overhauls—it’s about reliable, secure foundations. This release underlines a disciplined approach to LTS lifecycle management, balancing new hardware readiness with enterprise-grade stability.
