Ubuntu 24.04 Introduces Split Firmware Packages for Quicker Updates

Firmware updates in Ubuntu 24.04 LTS have become more efficient thanks to a new approach implemented by Canonical. The company has introduced the concept of split firmware packages, a feature initially released in Ubuntu 26.04.

The linux-firmware package now operates as a meta-package that encompasses various individual firmware packages rather than being a monolithic bundle. While users will continue to receive the complete set of firmware, the underlying structure has changed, allowing for updates on a smaller scale.

The firmware is now divided into 18 vendor-specific sub-packages, such as linux-firmware-intel-wireless, linux-firmware-nvidia-graphics, and several others tailored for different hardware components. This change means that when there is a minor security patch or bug fix needed, only the relevant sub-package needs to be updated, rather than downloading the entire firmware stack.

The previous configuration bundled many closed-source binary blobs from hardware vendors – essential for the proper functioning of various components like CPUs and network cards on Linux. The introduction of sub-packages means users can uninstall unnecessary firmware to free up space or manage system security better. For example, if certain firmware is not needed for a machine’s current setup, it can be removed without impacting essential functionality.

This redesign is a response to feedback and aims to minimize both the overall download size and the frequency of updates, thus alleviating pressure on Canonical’s update infrastructure. As a result, even users of the previous LTS version, supported with security updates until 2034, can enjoy these benefits of improved firmware management.
