Ubuntu 26.04 splits firmware package to reduce update sizes

Ubuntu 26.04 LTS (Resolute Raccoon) Revolutionizes Firmware Updates with Vendor-Specific Package Splitting

In a bold move that’s set to redefine how Linux distributions handle hardware support, Ubuntu 26.04 LTS—codenamed “Resolute Raccoon”—is completely overhauling its firmware update system. The change addresses one of the most persistent pain points in the Ubuntu ecosystem: bloated firmware updates that waste bandwidth and strain infrastructure.

The Problem: A 500MB Albatross Around Every User’s Neck

For years, Ubuntu has shipped all firmware files in a single monolithic package called linux-firmware. This approach, while simple, has become increasingly problematic as the package has ballooned to over 500MB in download size, consuming up to 1GB of disk space when installed. The situation has grown so severe that even minor security patches trigger massive downloads for every single Ubuntu user.

Here’s the real kicker: when a tiny 100KB security fix is released for specialized hardware like Netronome or Mellanox network cards—equipment primarily found in enterprise data centers—every Ubuntu user worldwide must download the entire 600MB+ update package. It’s the technological equivalent of repaving an entire highway just to fix a single pothole.

Infrastructure Under Siege

Canonical engineer Juerg Haefliger highlighted the severity of the situation, noting that firmware security updates land in the -security repository, which isn’t mirrored for security hygiene reasons. This creates a perfect storm where “the whole world is hitting a single server at the same time” whenever a firmware update is released.

The strain on Ubuntu’s infrastructure is immense. Each major firmware update triggers a global bandwidth tsunami as millions of devices simultaneously attempt to download hundreds of megabytes of data, most of which they don’t actually need. This isn’t just an inconvenience—it’s a fundamental inefficiency that impacts system performance, network resources, and Canonical’s operational costs.

The Solution: 17 Specialized Packages for Precision Updates

Ubuntu 26.04 LTS introduces a revolutionary meta-packaging approach that splits the monolithic linux-firmware package into 17 carefully curated sub-packages. This architectural shift represents years of planning and addresses a bug filed way back in 2022.

The new package structure includes:

• linux-firmware-mellanox-spectrum for enterprise networking hardware
• linux-firmware-intel-wireless for Intel Wi-Fi and Bluetooth devices
• linux-firmware-intel-graphics for Intel integrated graphics
• linux-firmware-amd-graphics for AMD Radeon and integrated graphics
• linux-firmware-nvidia-graphics for NVIDIA discrete graphics cards
• linux-firmware-intel-misc for various Intel components
• linux-firmware-broadcom-wireless for Broadcom networking hardware
• linux-firmware-netronome for high-performance networking
• linux-firmware-misc for miscellaneous hardware support
• linux-firmware-qlogic for enterprise storage and networking
• linux-firmware-marvell-wireless for Marvell wireless devices
• linux-firmware-mediatek for MediaTek components
• linux-firmware-marvell-prestera for data center switches
• linux-firmware-realtek for Realtek networking and audio
• linux-firmware-qualcomm-wireless for Qualcomm wireless hardware
• linux-firmware-qualcomm-graphics for Qualcomm graphics solutions
• linux-firmware-qualcomm-misc for miscellaneous Qualcomm components

How It Works: Targeted Updates, Massive Savings

The genius of this approach lies in its precision. Most of these packages will remain installed by default to ensure Ubuntu 26.04 LTS maintains broad hardware compatibility out of the box. However, when firmware updates are released, only the specific packages containing changed firmware need to be downloaded.

Imagine a scenario where Intel discovers a security vulnerability in their wireless drivers. Under the old system, every Ubuntu user would download 600MB+ of firmware updates. With the new system, only users with Intel wireless hardware would download the relevant package—likely just a few megabytes containing the actual fix.

All packages remain grouped under the linux-firmware umbrella as an overarching meta-package, ensuring that users who want the complete firmware suite can still install everything with a single command. But for everyone else, updates become targeted, efficient, and significantly smaller.

The Technical Brilliance

This change represents more than just splitting packages—it’s a fundamental rethinking of how firmware distribution should work in modern Linux distributions. By creating vendor-specific packages, Ubuntu achieves several critical objectives simultaneously:

First, it dramatically reduces bandwidth consumption across the entire Ubuntu user base. Instead of millions of users downloading hundreds of megabytes for minor fixes, only affected users download small, targeted updates.

Second, it alleviates pressure on Canonical’s infrastructure. The single-server bottleneck that occurs when firmware updates are released becomes a thing of the past, as update traffic is distributed across multiple package repositories.

Third, it improves security update responsiveness. Smaller packages mean faster downloads, quicker installations, and more users staying current with security patches.

Timeline and Availability

The change is already rolling out to Ubuntu 26.04 development builds, with Canonical engineers closely monitoring the implementation. Assuming no major issues arise during testing, this new firmware architecture will be fully implemented when Ubuntu 26.04 LTS officially launches in April 2026.

Why This Matters for Everyone

Whether you’re a casual Ubuntu user, a system administrator managing enterprise deployments, or a developer building applications on Ubuntu, this change has significant implications. Faster, smaller updates mean less time waiting for system maintenance, reduced data usage for users with limited bandwidth, and more efficient use of network resources globally.

For enterprise users, the benefits are even more pronounced. Data center operators who rely on specialized networking hardware will no longer burden their entire user base with updates that only affect a tiny fraction of machines.

The Future of Firmware Management

Ubuntu’s bold move with Resolute Raccoon could set a new standard for how Linux distributions handle firmware. As hardware ecosystems become increasingly complex and security requirements more stringent, the old monolithic approach simply isn’t sustainable. Ubuntu’s vendor-specific packaging model offers a scalable, efficient alternative that other distributions may soon adopt.

This isn’t just an incremental improvement—it’s a fundamental shift in thinking about how operating systems should manage hardware support. By treating firmware as a collection of specialized components rather than a single monolithic entity, Ubuntu is paving the way for more efficient, secure, and user-friendly Linux distributions.
