Canonical has released Ubuntu 24.04.5 LTS, delivering a refreshed installation image that incorporates security updates and fixes for high-severity bugs affecting the long-term support “Noble Numbat” release.
For New Zealand organisations, developers and home users deploying Ubuntu on new systems, the point release means many previously issued updates are now included directly in the installation media, reducing the amount of downloading and patching required after setup.
Ubuntu 24.04.5 LTS Focuses on Security and Stability
Ubuntu 24.04.5 LTS is primarily a maintenance release rather than a major feature upgrade. Canonical has concentrated on security corrections and stability improvements, reflecting the priorities of an LTS release designed for systems expected to remain in service for several years.
Users performing a fresh installation with the latest media will receive those accumulated fixes from the outset. This can be particularly useful for businesses, public-sector organisations, educational institutions and IT teams managing multiple Ubuntu devices, where reducing post-installation updates can simplify deployment.
The release covers more than the standard Ubuntu Desktop and Server editions.
Nine Additional Ubuntu Flavours Receive Updates
Nine other official Ubuntu flavours have also moved to version 24.04.5. These include Kubuntu, Xubuntu, Ubuntu MATE, Ubuntu Studio and Edubuntu.
Each flavour maintains its own release notes covering changes specific to its desktop environment, applications and other components.
The broader rollout means users across the Ubuntu ecosystem can access updated installation media rather than having to install the original 24.04 LTS release and subsequently download a larger collection of patches.
Support Period Still Starts From Original 24.04 Release
The arrival of Ubuntu 24.04.5 does not reset the long-term support clock.
Ubuntu Desktop, Ubuntu Server, Ubuntu Cloud and Ubuntu Core receive five years of standard maintenance calculated from the original Ubuntu 24.04 LTS release, rather than from the availability of this latest point release.
Other official Ubuntu flavours receive three years of support, also measured from the original 24.04 launch.
That distinction is important for New Zealand businesses and IT administrators planning hardware refresh cycles, server deployments or long-term software support requirements. Installing Ubuntu 24.04.5 provides the latest consolidated installation media, but it does not extend the underlying standard maintenance period.
Users and organisations requiring security coverage beyond the standard support window can use Canonical’s Expanded Security Maintenance offering.
Ubuntu 22.04 LTS Users Have an Upgrade Path
Existing Ubuntu 22.04 LTS installations do not need to be replaced simply to obtain the fixes incorporated into the latest release.
Ubuntu’s Update Manager provides an automatic upgrade path to Ubuntu 24.04.5, allowing eligible systems to move to the newer LTS generation without requiring a fresh installation. Canonical continues to provide Ubuntu version upgrades free of charge.
For administrators, the choice between upgrading an existing installation and deploying the new 24.04.5 media will largely depend on operational requirements rather than access to the security corrections themselves.
Detailed Patch Information Available in Release Notes
The main Ubuntu 24.04.5 announcement does not individually identify CVEs or bug IDs addressed by the release.
Administrators who need to verify whether particular vulnerabilities or software defects have been patched — including organisations operating under formal security or compliance requirements — will therefore need to consult the detailed release documentation for the relevant Ubuntu edition or flavour.
Fresh Installation Can Reduce Post-Setup Downloads
For most users, there is relatively little difference in the final result between installing Ubuntu 24.04.5 from the refreshed media and allowing an existing supported installation to receive its updates normally.
Both approaches ultimately deliver the relevant fixes.
The main advantage of the new installation media is convenience. A fresh deployment starts with more current packages already included, reducing the volume of updates that may need to be downloaded immediately after installation. That can be useful when deploying multiple computers or working with slower or constrained internet connections.
Existing installations can instead continue receiving packages through Ubuntu’s regular update process without requiring reimaging.
Ubuntu 24.04.5 LTS therefore serves primarily as a consolidated security and maintenance milestone for Noble Numbat. It makes fresh deployments more efficient while keeping the original Ubuntu 24.04 LTS support timetable unchanged.
