Canonical has released Ubuntu 24.04.5 LTS, an update to its Noble Numbat long-term support distribution, which integrates security updates and stability fixes directly into new installation media. This point release aims to reduce the number of post-installation updates for new deployments.
The 24.04.5 release encompasses not only the standard desktop and server editions but also nine other official flavors, including Kubuntu, Xubuntu, Ubuntu MATE, Ubuntu Studio, and Edubuntu. Each of these flavors has its own specific release notes detailing flavor-specific changes alongside the core updates.
Canonical emphasized that the primary focus of this LTS point release is on security corrections and stability improvements, which are critical for a version designed for long-term deployment. Existing users of Ubuntu 22.04 LTS will be offered an automatic upgrade path to 24.04.5 through the Update Manager, which Canonical confirms will remain a free upgrade.
For those planning deployments, it is important to note that the support timelines are tied to the original 24.04 LTS release date, not this point release. Ubuntu Desktop, Ubuntu Server, Ubuntu Cloud, and Ubuntu Core are supported for five years from the initial 24.04 launch. The other flavors receive three years of maintenance. Users requiring support beyond these periods can opt for Expanded Security Maintenance.
Administrators considering whether to perform fresh installations with the 24.04.5 media or allow existing installations to update through their normal cycle should understand that the fixes will reach both paths. The main difference is that new installations using the 24.04.5 media will have these corrections pre-applied, saving a round of downloads immediately after setup.
The release notes for Ubuntu 24.04.5 do not explicitly list specific CVEs or bug IDs. Administrators needing to verify particular patches for compliance purposes are directed to consult the linked release notes for more detailed information.
