So many good things ...

Today we'll be talking about the software we love to ship in Bluefin.

Bazaar​

Bazaar is the application store on Bluefin systems. It is designed to bring the best of Flathub to your fingertips, with a focus on directly supporting application authors. It accomplishes this by focusing on highlighting donations to app authors and ensuring that you get those applications as soon as they are released upstream. No jank.

We're proud to ship this as our app store. Flathub has over 1 billion downloads and 21% Year over Year growth. Nice.

We can't get there from here without a working delivery platform — please donate to Bazaar. Built by @kolunmi and @AlexanderVanhee.

Homebrew Applications​

The ublue-os/tap is the production Homebrew tap for Bluefin - a curated collection of software packaged to work great on all Linuxes. Run ujust bbrew to open the interactive browser and install anything from the tap in a few keystrokes. Here are the highlights of apps added over the last cycle:

Editors and IDEs​

• Visual Studio Code — Microsoft's open-source code editor. You can now install this without needing to use a DX image
• VS Code Insiders — The daily preview build of VS Code with the newest features.
• VSCodium — VS Code binaries built without Microsoft telemetry or branding.
• JetBrains Toolbox — Install, update, and manage every JetBrains IDE from one app. This installs Jetbrains into your home directory as intended by Jetbrains.

System Tools​

• framework-tool — Official CLI for Framework laptop hardware: fan control, battery charge limits, charge LED mode, input module configuration, and firmware update checks.
• heic-to-dynamic-gnome-wallpaper — Convert macOS HEIC dynamic wallpapers into GNOME XML dynamic wallpapers that change with the time of day.
• pmbootstrap — The sophisticated chroot/build/flash tool for postmarketOS development and porting Linux to mobile devices.
• asusctl — CLI and daemon for ASUS hardware: fan curves, battery charge limits, keyboard LEDs, GPU mode switching, and more.
• ROG Control Center — GUI front-end for asusctl, providing a graphical interface for all ASUS ROG hardware controls.

The operating system usage is also interesting. One of the reasons we picked homebrew was to be in the same group as everyone else. It's also nice to know that we're helping represent Linux:

Bluespeed​

Bluespeed is our catch all term for agent-centric tooling in Bluefin. It is a play on RHEL Lightspeed, Red Hat's tooling in this area. We continue to collaborate with the team and ship their tooling, such as linux-mcp-server. Bluefin ships a full cloud and AI native development platform ready to go. We default to a "Bring your own LLM" approach, with a focus on pushing towards an all-local opt-in approach for system troubleshooting.

Our flagship tool is Goose from the Agentic AI Foundation, which serves as our "portal" to other tooling. We recommend using the ramalama tool for model management. This features full GPU acceleration for NVIDIA and AMD GPUs to work with local models out of the box. Models and drivers are kept in containers for flexibility. It's an awesome set up, give it a shot!

Full AI setup guide →

Agents and Tools​

Run ujust bbrew to install any of these:

• Goose — The primary AI agent in Bluefin, from the Agentic AI Foundation (AAIF). Open source, extensible AI agent that goes beyond code suggestions.
• LM Studio — Discover, download, and run local LLMs.
• Antigravity — AI Coding Agent IDE.
• Cursor — Write, edit, and chat about your code with AI.
• Craft Agents — Work with most powerful agents in the world, with the UX they deserve.
• OpenCode Desktop — Open source AI coding agent desktop client.
• Emdash — Agentic development environment for running multiple coding agents in parallel.
• Ramalama — Goal of RamaLama is to make working with AI boring.
• Alpaca — A graphical LLM chat interface available as a Flatpak. Launch it instantly from anywhere with Ctrl+Alt+Backspace.

Agent CLI Tools​

Ask Bluefin (Alpha)​

Ask Bluefin is a natural-language system assistant that can diagnose, explain, and help troubleshoot your machine using our community's data. You can hit it up on the website, the dedicated discussion forum, the soon-to-come shortcut in the menu, and the soon-to-come Discord app.

Ask is done in partnership with Dosu - here's the gist. Ask Bluefin is trained on all of the documentation and source code for all of the tooling in Bluefin, Bluefin's source code, issues, documentation, and discussions. Podman, bootc, vscode, systemd, etc. Everything on your system. AND THAT'S IT. It is only trained on the code and docs. The results are usually much better than a generic LLM, and light years ahead of Linux subreddits. (That's not a high bar, but let's have some goals). I have it write service units for me, because the era of writing these by hand is now almost over.

Dosu also runs an MCP server if you want to connect your clients to it or work on apps that can index our community's collective knowledge.

Troubleshooting (Alpha)​

Proprietary operating systems are falling over each other trying to implement the worst possible anti-privacy features with AI. Of course they are, it's the nature of the beast. We take a different approach. If someone's going to invent this thing, then we're going to use it for good. Our first stab at this is to use it for a more natural goal - fix broken computers. (Computers are awful)

linux-mcp-server is an MCP server that gives any AI agent live read only access to your system: OS info, processes, services, logs, network, and filesystem. When connected to Goose it gives your LLM access to the following features:

• "Bring Your Own LLM" — use it with a local Ramalama model for fully offline diagnostics, or connect to a hosted API for more capable reasoning — same data, your choice. Current this works best with paid frontier models, but also has been working great with the cheaper "fast models". Our team continues to experiment with the latest local models. Our final goal is for your computer to be able to diagnose itself with 100% local workflows on open weight models. Kyle Rankin in particular is going hard on this and has been making some incredible progress. It's only a matter of time, open always wins.
• Natural language diagnostics — Ask questions like "why is my fan running loud?" or "what process is eating my RAM?" and get real answers grounded in your actual current system state
• Works with any MCP-compatible agent — Goose, OpenCode, and any client that supports the Model Context Protocol can connect to linux-mcp-server and get the same system access
• (Optional, requires setup) Bluefin knowledge base built in — Dosu integration means the assistant already knows the Bluefin documentation, common issues, and community-reported workarounds.

I became a fan when on a trip to the Southern California Linux Expo. My computer was acting weird. I had the tool diagnose the problem, ends up we had made an error in our swap config for Bluefin LTS. It confirmed the issue, and then linked me to the existing issue that someone had reported a few hours before. Clanker + Human confirmation found the issue. We rolled out a fix. I am never going to diagnose a Linux machine by hand ever again.

New Art​

My favorite part of Bluefin, the artwork! I'd like to thank the two new major donors who are funding two new future Bluefin renditions. The future is bright for more art!

Lazy Days

by Jay Balamurugan

Jay joins the prestiguous list of paleoartists to render Bluefin. Jay is a London-based science communicator, paleoartist, and television producer — her credits include Earth, Walking with Dinosaurs, and Evolution.

Bluefin was first modelled in Blender, similar to the technique used in Walking With Dinosaurs, before the finishing work added the feathers. This is so cool! Dinosaurs are typically portrayed as blood thirsty killers murdering constantly. But like real animals there are plenty of times when all you want to do is lay down. This rendition of Bluefin reflects a more chill day, a full belly, and no worries.

You can follow her on Bluesky and Instagram.

Sunrise

by Amy

Sunrise is an older wallpaper from Amy that we failed to ship and announce. Sorry about that Amy!

Sunrise is now available for those of you that prefer your Bluefin smol.

Leaf Collector

by Dr. Natalia Jagielska and Delphic Melody

Did you know birds once had teeth? Crazy I know. This is another banger from Dr J and Delphic. Delphic has painstainkingly vectorized the original artwork so that we can enjoy this artwork on any size monitor.

Duality

by Dr. Natalia Jagielska and Delphic Melody

Duality is a modified Leaf Collector designed for ultra wide monitors. It looks spectacular on 21:9 monitors.

Eyes

by Dr. Natalia Jagielska and Delphic Melody

Our last wallpaper from Dr. J is one of my favorites. It features a microraptor hunting a poor butterfly. Did she catch it? We'll leave that interpretation up to you.

Install the Wallpapers​

The default wallpapers ship automatically with Bluefin. The extra collection (Leaf Collector, Duality, Eyes, Lazy Days) is available via Homebrew:

brew install --cask ublue-os/tap/bluefin-wallpapers-extra

Wallpaper Packs​

Extra wallpaper collections for every variant — install the ones that match your image. You only need the first one if you're not on Bluefin:

brew install --cask ublue-os/tap/bluefin-wallpapers
brew install --cask ublue-os/tap/bluefin-wallpapers-extra
brew install --cask ublue-os/tap/aurora-wallpapers
brew install --cask ublue-os/tap/bazzite-wallpapers
brew install --cask ublue-os/tap/framework-wallpapers

Documentation Improvements​

We've been working pretty hard this cycle on the docs. Specifically around getting more information of what's in Bluefin so that we can be more transparent about what we ship:

Changelogs

Automated weekly changelogs for every image stream

This page will show you all of the versions and releases of every Bluefin. It is automatically generated from Bluefin's Software Bill of Materials (SBOM), so it will always show you what's on the image. This took way more work than we realized, but thanks to awesome tools such as <a href="https://oras.land">oras</a> and <a href="https://github.com/sigstore/cosign">cosign</a> we now have a nice way to show you what's in Bluefin. We also include the updates from the default homebrew and flatpaks shipped in Bluefin for convenience.

Monthly Reports

What's going on?

This page aggregates all of the work from the volunteers that are landing in Bluefin. This report is generated monthly and features all of the contributors who work on Bluefin. My favorite feature is it highlights people's first contribution as a milestone. Welcome aboard, Guardian.

Images

Full matrix of available image variants

This page is a reference of all of the images we publish, and features rebase instructions if you need them. This includes the testing branches of every image (if they exist), as well as the Nvidia images.

Driver Versions

GPU driver version tracker across streams

Ever update and get a regression? When was the last kernel update? When was the last time Uncle Jensen left us an unexpected gift? This page shows a matrix of major component version bumps so you can quickly see what updated when so you can at least make a better guess as to what past image you should rebase to. This page is clutch for troubleshooting.

Music

Metal, Mayhem, and Melancholy

Every release ships with a curated soundtrack highlighting Bluefin's cloud native journey. The music page archives every playlist we have released, with notes on the artists and the vibe we were going for.

Artwork

Browse and download all wallpapers and artwork assets

Bluefin is not just tech, the artwork of her world is just as important to us as the software.<br/><br/>All of Aurora and Bazzite's wallpapers are also available here, in dark and light variants.<br/><br/>All of Bluefin's artists are compensated for their work. Bluefin will never ship AI generated art.

Downloads

Refreshed Downloads Page

The downloads page provides direct ISO links with checksums and torrents for every Bluefin variant — Bluefin, Bluefin LTS, and Dakotaraptor — with GPU-specific entries so you always grab the right download when you need it!

Metrics​

Charts! My favorite. Usage remains steady at about 3.5k weekly devices. This feels about right for our target audience, but Bazzite is still 10x larger. And Ubuntu even more so. I've personally really never cared too much about this - you always need to make the contributor and team structure healthy before these numbers can ever go up.

This is the year that Aurora and Bluefin will start to focus on this number.

Contributor Community​

Unfortunately due to limitations in LFX, we can only track one Bluefin repository - so the charts below reflect the reduction of contributions to the one monorepository. This is a bummer because we intentionally split the project up into more granular repositories. The work in all other Bluefin repositories is NOT tracked here. When we can aggregate all of the contributions across all repositories we will have better data. It's all in git so we will be able to come back and correct past charts. Here are the numbers anyway:

Discussion Thread​

Two hats and a dromeosaur

^^^ this post best enjoyed with heavy metal.

I found this app called Speed of Sound, a speech to text app that makes writing long winded release announcements a breeze - so this is a series of blog posts over the next three days.

I am not going to lie I haven't been this excited about Bluefin since the start of the project. This spring is particularly relevant for us, with GNOME 50 being a particularly nice roll up of tech. First more of a project update. As I've alluded to in the past, we're learning to come out of the shadows more for people looking for a great desktop for every day use. We've purposely avoided this audience for a few reasons - mostly because normal people don't install operating systems.

But now that we've got five years of production under our belt it's probably time to be louder. First we're partnering with Michael Tunnell on a set of video content that should be more appealing to the general computing audience. Then you can expect more visible changes in our approach as we (as they say in the biz) "Go To Market". Expect that some time this summer!

Lazy Days​

This is Lazy Days by Jay Balamurugan. Jay is a London-based science communicator, paleoartist, and television producer — her credits include Walking with Dinosaurs and Earth. This is Bluefin as you rarely see her: full belly, no worries, just a chill day in the sun.

Some backstory ...​

Some of you know that Bluefin wasn't really an accident - it's a distillation of decades of OSS experience from a bunch of experienced people. I am particularly priviledged to be exposed to this audience of open source gurus. Part of our appeal is we get you one step closer to knowing how Open Source actually works from the people doing it at the professional level. We're taking this team-work based approach to the maintenance of our desktops. That's basically it. Here are the collective lessons we have learned:

• Digital Sovereignty: There is an actual demand for a Linux client that can be built, from the ground up and verified to the very end. We're not talking about what you would typically consider "an Ubuntu remix". It's gotta be at the top level of supply chain security and be deployable at scale. Only modern Linux can compete here.
• Bazzite proves that delivering to the 95% is a thing people want
  • Ends up that there's significantly more to gain by throwing away the old things holding Linux back than serving edge cases.
• Open Gaming Collective has proven that different distributions can work together in a way that is conducive to get all of this stuff out of the little fiefdoms and into the upstream Linux kernel. And they're just getting started.
• The Team:
  • Seven(!) people have gotten jobs through Universal Blue.
    • Chainguard, Red Hat, and Microsoft have all recognized the talent from the enthusiast community. Users like you have proven to the industry that enthusiasts matter.
  • It's not about what we're building these days, it's about what we're choosing to NOT build.
  • Ends up that the development techniques from Open Source infrastructure apply very well to people who love to work together as a team. You don't succeed in this business as an individual, you bring your individual talent to a team, and you succeed together.
• Efficient downloads are coming: It never made sense to push too hard with this limitation. Now it's not going to be an issue. I'll explain more in the third blog post.

I find digital sovereignty in particular to be interesting. The discussions around Linux are predictable. Once again people are fighting over who is going to ship the least-worst Debian. The discussion should be focused on infrastructure and how you build it. You know who are really passionate about infrastructure? The European Cloud Native communities. The Kubernetes nerds expect and demand a modern Linux, and in order to deliver that you need world class infrastructure. The communities are mixing, and with modern tooling like bootc and buildstream the bare minimum standard for what constitutes a Linux desktop is about to go up substantially. So yeah, it's probably time to be louder.

But enough preaching, let's go into how we plan to get you there!

GNOME 50 "Tokyo" comes to Bluefin​

GNOME 50, codenamed Tokyo, is the foundation of this release. If you're updating today you'll be on GNOME 50. It is opt-in in Bluefin LTS:

ASUS Support​

Asus support has always been a pain in the ass on Linux. In the past we had specialized images but the maintenance burden was too great. Thanks to improvements in Linux 6.19 and greater, as well as awesome work from the asus-linux community we can now better support Asus hardware. The Asus Linux community is a participant in the Open Gaming Collective, which gives us the confidence that this will be well maintained over time. Thanks so much for your efforts!

The ublue-os/tap ships asusctl and ROG Control Center — the standard ASUS Linux control stack. These packages will work on any Linux with at least a 6.19 kernel.

• Fan curve control — per-profile fan curves for Performance, Balanced, and Quiet modes; customizable RPM targets per temperature point
• Keyboard RGB and Aura lighting — full per-key RGB control, multi-zone effects, static, breathe, rainbow, strobing, and more — all manageable from the GUI or CLI
• Power profile switching — toggle between Performance, Balanced, and Power Saver without a reboot
• Battery charge limit — set a charge ceiling (e.g. 80%) to preserve long-term battery health; the limit persists across reboots
• GPU mode switching — switch between Integrated, Hybrid, NVIDIA-only, and Compute modes from the system tray
• This is in Bazzite's testing branch as ujust asus and we'll pick it up at some point. Sorry that you have to do this by hand:

Install (order matters — system daemon first, then the GUI):

# Step 1: system daemon — handles hardware access and power management
brew install --cask ublue-os/tap/asusctl-linux
sudo systemctl enable --now asusd.service asus-shutdown.service
sudo udevadm control --reload && sudo udevadm trigger

# Step 2: GUI and user daemon
brew install --cask ublue-os/tap/rog-control-center-linux
systemctl --user daemon-reload
systemctl --user enable --now asusd-user.service

ROG Control Center lands in your system tray and gives you a full GUI for everything above — no terminal required after the initial setup. Someday we will automate this so you don't have to do any of this CLI mumbojumbo, but in the meantime kick the tyres and report back. Remember that these packages work on any Linux!

This support has turned my 2022 G14 AMD Advantage Edition in a pretty great Linux laptop. It wasn't always like that!

Bluefin​

Now on to Bluefin itself. First up is bluefin:stable. Here's the release card:

And here are the release notes and announcements:

• Fedora 44 Release Notes
• What's New for Fedora Atomic Desktops in Fedora 44

And that's it. The usual stuff. I want to focus on what's coming next because Bluefin is going to change for the better.

The Future of Bluefin and Fedora​

Timothée Ravier's post is particularly relevant for us. The biggest news of all is the announcement of new sealed base images. These will end up being the most fundamental change to Bluefin in its 5-ish year history. The new sealed bootable container images will bring us:

• systemd-boot replaces GRUB as the bootloader — GRUB is now an extinct species in our world. Goodbye old friend.
• Unified Kernel Images (UKI) — kernel, initrd, and command line bundled into a single signed EFI binary.
• composefs with fs-verity — every file in the OS image is cryptographically verified at read time and managed by bootc. We also say goodbye to ostree. With both projects now in the Cloud Native Computing Foundation we have a vendor neutral stack to base Bluefin on. Nice.
• Full verified boot chain from firmware → bootloader → kernel → OS image — see the FOSDEM 2025 deep-dive for how it all fits together
• TPM-backed passwordless disk unlocking via systemd-cryptenroll — LUKS unlocking is bound to the verified boot state so no password prompt on a clean boot
• UEFI on x86_64 and aarch64 - Legacy BIOS support goes away too, but we don't support that anyway.

Want all of these things? It will take some work to move Bluefin and Aurora to these new base images, and we're looking for people to help. If you've been worried about the lack of progress in bootc in Fedora then this one set of images brings us back to the forefront of Linux desktop tech. Our man from France was not going to let Dakotaraptor run away with it, so if you want to help make this dream a reality, now is the time to step up and volunteer!

Fedora Accelerates​

The biggest improvement this cycle has been mostly invisible to you. Fedora's bootc efforts seem to have been finally resolved. It may come as a surprise to some of you that Fedora does not actually release an official bootc image. All of our work continues to be based on Timothée's unofficial images. For the first time it feels like Fedora have figured out what to do with bootc, and this removes a bunch of uncertainty for us. It has never made sense that Fedora would start off in the lead and end up behind the rest of the community with bootc adoption. This also means that if you're enjoying Aurora, Bazzite, Bluefin, Secureblue, or rocking your own custom image ... quality is going to go up.

Honestly I just work on Fedora to toss RPMs right at Jorge's smug cloud native face.

-- John Bazzite

It took lots of work to get Fedora back on track with bootc, after all, Bluefin was intended to be a weekend project inbetween Fedora 39 and 40 to prove how easy it was. See? Look how easy that was! Jef you're doing great, I'm sorry for riding you so hard over the past few months. Fedora has two awesome avenues and a brand new sandbox to play in -- good to see some "Fedora First" flexing over there! Thanks Laura Santamaria and LH!

They have a ton of work to do, so if this is your jam, now is the time to get involved. Good timing too, looks like Red Hat is hiring.

An awesome special thanks to the Fedora CoreOS team for ensuring the Copy Fail 2 and DirtyFrag issues were resolved in the kernel we use. I also have some awesome Fedora news for you ... tomorrow.

Bluefin LTS​

Now over to CentOS -- Achillobator giganticus remains our Long Term Support option, here's the release card:

Bluefin LTS launched with GNOME 48 and has been updated to GNOME 49. This release delivers two full GNOME upgrade cycles in one — GNOME 49 and GNOME 50 are both available — thanks to @hanthor's work backporting the full GNOME stack to the EL10 base. See the March testing announcement for all the details.

There's really not much to say here, the move to GNOME 49 wasn't as smooth as we'd like but as a result GNOME 50 is much smoother. We will keep GNOME 50 in it's own set of branches and likely move LTS to GNOME 50 sometime this Fall.

Bluefin LTS is maintained by @hanthor. If you rely on the LTS channel, consider supporting his work:

Merch​

Unfortunately selling outside the US is still a struggle, we'll continue looking at options. Our store is designed to highlight Bluefin's incredible artists! Proceeds from the store fund future artist work. We adjust the prices on all the other items in the store in order to make the kids shirt as cheap as possible. Rawr.
