OMG! We’re at forty! (Announcing the release of Fedora Linux 40)

Image contributed by Consolation Obazee

Oh, wow. This feels like a big number! I’m proud to announce the 40th release of Fedora Linux, a community-built and community-maintained operating system that belongs to all of us. I’m also happy to note that we’re back on track with an on-time release. Thank you to all Fedora contributors who made that possible, and who have, yet again, made this our best one ever.

This is also a personally exciting number for me, because this marks the 20th release for which I’ve served as Fedora Project Leader. We’ve gone through a lot in this last decade, and I’m incredibly happy to see our community thrive and grow. In addition to many long-familiar names and faces, it’s exciting to see a new generation with new energy and ideas. In some cases, this is literally a new generation, as many of you have grown up with Fedora. But at whatever age, I’m proud we’ve built such a welcoming and friendly community, and that we continue to work at improving our inclusiveness, diversity, and accessibility.

But anyway! Enough of that. Time to see what we’ve got for you in Fedora Linux 40! If you have a system already, Upgrading Fedora to a New Release is easy. If you’re new, or just curious, head to Get Fedora for installation options.

Desktop news

Fedora Workstation Edition features the GNOME desktop environment, now updated to version 46. Check out What’s New in Fedora Workstation 40? for the highlights!

The KDE Spin now includes KDE Plasma 6, and runs with Wayland out of the box. Read more about that and other KDE Spin updates at What’s New in Fedora KDE 40?

We’re also officially reviving the “Fedora Atomic Desktop” brand for all of our variants which use ostree or image-based provisioning. Our technology isn’t really “immutable”, so this provides a better grouping. Read more about this at Introducing Fedora Atomic Desktops — but in short, Fedora Silverblue and Fedora Kinoite will remain, while the other desktop  variants will become Fedora Sway Atomic and Fedora Budgie Atomic.

Tools for AI development

Fedora Linux 40 ships with our first-ever PyTorch package. PyTorch is a popular framework for deep learning, and it can be difficult to reliably install with the right versions of drivers and libraries and so on. The current package only supports running on the CPU, without GPU or NPU acceleration, but this is just the first step. Our aim is to produce a complete stack with PyTorch and other popular tools ready to use on a wide variety of hardware out-of-the-box.

We’re also shipping with ROCm 6 — open-source software that provides acceleration support for AMD graphics cards. We plan to have that enabled for PyTorch in a future release.

Updates all around!

As usual, we’ve rebuilt everything in the distribution using updated compilers and libraries (and, of course, those updated tools are ready for developers to use). These updates bring bugfixes, security improvements, and performance gains.

And, of course, hundreds of Fedora packagers and testers have worked to integrate the latest versions of open source software from thousands of upstream projects. Those projects, in turn, are made by an uncountable number of developers and contributors working on marketing, design, documentation, code, quality, translations, communications, events, governance, infrastructure, security, and so much more. Thank you again to everyone who makes Fedora amazing, and to everyone whose work has built this whole universe of free and open source software.

Speaking of updates…

There are several important release-day bugfix and security updates available today as well. If you upgrade from an earlier Fedora Linux release, you’ll get them as part of that. For new installations, please make sure to check for and apply updates as soon as possible.

In the unlikely event of a problem…

If you run into a problem, visit our Ask Fedora user support forum. This includes a category for common issues

Or if you just want to say “hello”…

Drop by our “virtual watercooler” on Fedora Discussion and join a conversation, share something interesting, and introduce yourself.

Also, remember that our annual contributor conference, Flock To Fedora, is coming up! It’ll be in Rochester, New York this August. The call for session proposals is still open, if you have something you’d like to share or work on. If you’re already a Fedora contributor, or are interested in being one, or think you might be, we’d love to see you there!

    Great Job, everyone!

    I’ll be updating my work laptop later today and my home computer tonight!

    Then all the other people I’ve convinced to drop windows and use Linux full-time.

  2. Sudirman

    Kudos on releasing Fedora 40!

  3. Randy

    But why is Wayland broken in Fedora 40 Gnome edition? Drag n Drop between programs like Skype, Google Chrome and nautilus is simply hit and miss with Wayland. X11 works just fine but I thought Wayland was the next big thing but how can it not work on a Fedora 40 release???? WHY ???? I hav AMD video card using the default driver but I nee to use X11 if I want to get work done which is very disappointing.

    • Might be best to take your question to the Ask channel or the Matrix channel

    • sandalphonh

      Maybe Skype and Chrome don’t support Wayland, when I use Firefox, it works

    • user

      probably your google chrome is not using wayland. try going into chrome://flags and settings “Preferred Ozone platform” to “Auto” or “Wayland” directly and check if you still have problems.

      • AJCxZ0

        Be warned that the current version of Chrome – 124.0.6367.78 – has broken using Wayland this (correct) way, resulting in transparent windows.
        The workaround is to run using “google-chrome –enable-feature=UseOzonePlatform –ozone-platform=wayland”.

    • Roman

      All of these applications use Electron.

    • kiaumo

      The transparency of the Chrome window came up with Rawhide, and I think it’s Wayland’s problem

    It would be great if the benchmark on proper use of internet speed on Fedora competes with Windows.

    • Pawel

      If you want to find a worthy opponent for Windows, I would suggest MS DOS. Not sure if it connects to Internet, though.

    • Stan

      You will need to be more specific — Ethernet or WiFi?

      And Fedora packages two network speedtest tools:

      $ dnf -Cq repoquery speedtest*
      speedtest-0:1.3.0-1.fc39.noarch
      speedtest-cli-0:2.1.3-9.fc39.noarch

      Usage:

      $ speedtest-cli
      Retrieving speedtest.net configuration…
      Testing from [removed]
      Retrieving speedtest.net server list…
      Selecting best server based on ping…

  5. Congratulations to the team, contributors, and all Fedora users.
    I’m commenting right from Fefora Workstation 40!

  6. Fabrício Luís de Castro

    Greetings from Brazil!!!

    Great Job, everyone!
    Using since beta, rock solid!

  7. Scotty_Trees

    Excellente! Can’t wait to do a fresh install of F40 after reading all these updates. Thanks so very much to the devs, engineers, volunteers, and everyone else that just enjoys using and helping Linux continue to grow. Open source rocks!

  8. Paul Rockwell

    Still no ISO for arm64? Very disappointing.

  9. Mark

    Congratulations to all involved in the F40 release. 40 is a great milestone!

  10. SHAY

    Fedora you are doing the best job out there I am an electrical engineer otherwise I would help develop Fedora but I don’t know how to do it I hope to see WAYLAND in the MATE desktop which is the best there is in my opinion with Fedora of course

  11. james

    Gah, upgraded via rebase my silverblue x86_64 and it removed all my firefox settings so I lost all my logged in pages – all my streaming services were gone. Then I had to enable drm in the settings to get the widevine plugin to install, and then although netflix will play, amazon prime won’t. I am going to try installing mozilla-openh264, which I had to remove in order to upgrade, but as an introduction to fedora 40, and wanting to sit down and watch some tv with my dinner, I am fairly annoyed.
    What a shame, as the rest of it looks fine.

    • Greyzusht

      Hi James, I believe that the Flatpak version of Firefox on Silverblue and other atomic desktops will be more reliable. Additionally, it comes with all the required codecs.

  12. Ron

    Great Job!

    One question: Why are the labs projects (Astronomy, Games, etc) not available as a torrent download on torrents.fedoraproject.org?

  13. david

    Our server cluster are still in Fedora 38, I just hope it won’t break anything to pass to 39 and then 40. Long life to Fedora!

  14. Sean Redmond

    Updated a while ago and its amazing! Well done on this amazing release!

  15. Bruno

    Fedora is truly phenomenal. Everything you configure works perfectly without breaking and there is no need to redo the configuration to work again, almost like MS Windows. The only thing missing is support for external video adapters via USB (USB –> VGA)
    Specifically: MacroSilicon VGA Display Adapter. 🙂

    • Pawel

      You meant: unlike Windows. When there’s Windows update you have to pray to have usable computer after that.

  16. Matthew Phillips

    The upgrade went flawlessly! Thank you as always Fedora team!

  17. Ramon Barbosa

    Parabéns aos desenvolvedores pelo empenho de estarem sempre em constante trabalho no Sistema.

    Não tenho dúvida que este Lançamento estará bem melhor.

    Viva o Linux!

  18. Terrific release so far!

  19. Trung LE

    First and foremost, I would like to extend my gratitude to all people who make this release possible. Till date this is probably the best release for PowerPC64 LE architecture. My Blackbird Raptor workstation runs GNOME 46 with NO graphical slowness at all (FYI my GPU is AMD Radeon 6600XT).

    Btw, has anyone run into following issues when installing blender:

     Problem: conflicting requests
      - nothing provides libOpenImageIO.so.2.4()(64bit) needed by blender-1:4.0.2-1.fc40.ppc64le from fedora
      - nothing provides libOpenImageIO_Util.so.2.4()(64bit) needed by blender-1:4.0.2-1.fc40.ppc64le from fedora
      - nothing provides libboost_locale.so.1.81.0()(64bit) needed by blender-1:4.0.2-1.fc40.ppc64le from fedora
      - nothing provides libopenvdb.so.10.1()(64bit) needed by blender-1:4.0.2-1.fc40.ppc64le from fedora

    Congratulations for the whole Team! Enjoy it 🙂

  21. ReD

    Cheers! V40 is a nice release.
    I’m churning up upgrades as I write this!

    Thanks Fedora Team!

    Virtual machine enthusiasts will find a new cloud image:

    Fedora-Cloud-Base-UEFI-UKI.x86_64-40-1.14.qcow2

    That image implements unified kernels, which are embedded in EFI files. After updating:

    ll /boot/efi/EFI/Linux/

    total 87360
    -rwx——. 1 root root 44727112 Apr 24 01:47 [machine-id removed]-6.8.7-300.fc40.x86_64.efi
    -rwx——. 1 root root 44719944 Apr 14 22:56 6.8.5-301.fc40.x86_64.efi

    There are no kernels in /boot, and there is no grub.cfg file.

  23. Nosirjon

    great thx

  24. roy c hill

    Of course include pytorch. I assumed that api was so slow because I used it on a duo core processor because I was poor and still I was like.. [man… that stuff slow dude… ] with the new AI processors.. sure… maybe that is what pytorch needed is more cores to work with and I didn’t get it. Now maybe I should go back and learn python and stop thinking it is just a visual basic thing and make my hello world with pytorch…

  25. Harro Smit

    Fantastic Milestone! Fedora 40 sounds way better dan Fedora 39! Of course it’s just a number. But I already was on bèta 40 for a while and it was nice to see how several bugs where gradually wiped out, update after update!

  26. Zer0

    I guess it’s something deserving of toasts, greetings, and socially acceptable ultraviolence!! Cheers!

  27. Clive

    Yeah Booooooi!

    well done, congratulations on reaching the big 40

    been using fedora exclusively since Yarrow.

  28. MrMuno

    Linux newby here.. Just updated and now Wayland is not installed and Nvidia drivers seem to be missing…

  29. Londo

    A big thank you to everyone involved, i really appreciate all your work on Fedora 40. Started using the beta when it was released, and it’s been rock solid without a single issue from day one.

  30. asw15

    Very, Very good job.

    Many thanks. I love.

  31. Grandpa Leslie Satenstein

    Congratulations, Felicitations, Mazel-Tov, Felicidades

    A wonderful deliverable that goes beyond reasonable expectations.

    WOW!

    Thank you

  32. Grandpa Leslie Satenstein

    Matthew, there is a problem I have with multiple (2) installation of the the same Fedora 40. The two versions are KDE and workstation.

    Whatever version is installed second, causes the first installation to not appear in the boot menu. Same or separate SSDs.

    I have solved the grub.cfg issue with a modifcation to each of the “/etc/os-release.” I identified the one for workspace as such, and the /etc/os-release for KDE as such.

    Adding the word Gnome to the appropriate fields therein for the Workspace version and “KDE” to the second version solved the problem with

    When I do the final installation, I will be doing likewise.

    • Stan

      Ordinarily, you would enable os-prober in /etc/default/grub, but after extensive debugging, that mechanism appears to fail with btrfs when you have two disk drives, each with a btrfs filesystem, and each installed with default names.

      Try reinstalling with ext4.

      If you want to file a bug report, the component would be grub2.

      This is where the process appears to fail:

      grep -n ‘LINUXPROBED=.*btrfs’ /etc/grub.d/30_os-prober

      grub2-tools-2.06-121.fc40.x86_64

    • Grandpa Leslie Satenstein

      Cancel this message. Between the Betas and the production version, the issue I was having was corrected. All is well

    • Stan

      A simpler workaround than reinstalling with ext4 might be to rename the btrfs subvolumes to be the same. It might be possible to do that during installation.

      After manually mounting the btrfs subvolumes on vda3 while booted into the second system (on vdb), this shows how the subvolume names (e.g. “root” and “root00”) compare. Those names were all generated by the installer.

      $ lsblk -o PATH,FSTYPE,LABEL,FSROOTS,MOUNTPOINTS /dev/vda3 /dev/vdb3
      PATH FSTYPE LABEL FSROOTS MOUNTPOINTS
      /dev/vda3 btrfs fedora /root /run/user/1000/mount-point-vda3-root
      /home /run/user/1000/mount-point-vda3-home
      /dev/vdb3 btrfs fedora00 /home00 /home
      /root00 /

      /etc/fstab also shows them:

      $ fgrep subvol /etc/fstab

      NB: All this testing is being done in a virtual machine, hence the device names.

    mmmm, Fedora Atomic Desktop (FAD) 😉

  34. mk

    Wow, big fan of fedora. 40 unbelievable.. have been using since fedora core days… Improvements over the years are amazing. Outstanding effort ppl. Thank you.

  35. justsomeone

    Congratulations with Fedora 40!

    I have high hopes for Fedora 40 and the soon to be released new nVidia drivers. Together they should fix explicit sync issues in Wayland.

  36. Gerzal

    Tomorrow I will upgrade my beloved Fedora 🥰

  37. Tobin

    So Fedora 38 was a broken mess, Fedora 39 stablized quickly, and Fedora 40 is a broken mess again especially with KDE how it corrupted half the settings and overrode my preferences.

    I am done. Linux from Scratch is the only way to use a linux-based operating system the way it was intended to be used.

    • Pawel

      Fedora 40 is super smooth, stable and fast with Gnome. I bet you were upgrading from KDE 5 to 6. KDE 6 is a very big release and I suppose they broke some compatibility due to Settings rework.

      • Tobin

        I shouldn’t have to destroy my environment just for the next version.

      • Tobin

        You realize a more or less pure-gnome or per-kde create very different composite operating systems with the baseos and kernel once xorg or wayland are involved right?

        So I am glad you get a good experience. I had to fight, and scrounge, and bash fedora 39 into some form I could personally use something I couldn’t do on 38 and likely can’t on 40.

        Fedora is not a good experience for me and has never really been one either. I would argue it isn’t a good experience for anyone not afflicted with some sort of hyperactive constantly shifting crisis obsession and frameworks that support it (or a red hat employee). The kind that create new problems while TRYING to solve previous ones.

        I need stability, predictability, and most of all local command and control of my systems. Not more abstractions and layers. If any one system becomes too complex for the owner of that system or someone otherwise in charge of it cannot be able to not only reproduce that system but understand the majority of what they do and run. If it goes beyond that it doesn’t matter if it is Open Source or even Public Domain.. it becomes as out of reach to any one individual as the proprietary code such as Windows is.

    this will be my 31 fedora

    Somebody has to go and make an event in https://en.wikipedia.org/wiki/Fedora,_South_Dakota 🙂

  45. nanohe

    Cheers! V40 is a nice release.
    I already upgrade to this new version.

    Thanks Fedora Team!

  46. Jay

    OMG! i wish i was at 40 🙂

  47. Bry

    Wow great. Easy upgrade.

  48. My transition to F40:
    1. Postgresql service would not start. Apparently F40 upgrades from 15 to 16. All of the binaries defaulted to 16 but could not find a proper install. I had to move my database to a temporary location to get the service to startup. Had to rebuild my environment.
    2. MariaDb service would not start. It appeared that the binaries were upgraded to 10.11 but the service was not. Reinstalled to get the service to start. Unfortuately, the restart wiped my database and configuration. Had to rebuild.
    3. Was using Evolution for my email. the GOA:google authorization failed. Cannot figure out how to repair. I have 69 views at ask-fedora but no answers. See: F40 – evolution/keyring, accounts using GOA:google. Had to convert to Thunderbird, although I prefer the no nonsense Evolution front-end. I guess an old dog can learn new tricks.
    This was not a pleasant upgrade….

  49. Matt C

    Was a bit worried upgrading after KDE plasma would not load like it did every other upgrade since ~35, but I am not on the KDE flavor, so I had to run GNOME to upgrade each Plasma-related package group.

    Now its running perfectly on Plasma 6 and is probably the smoothest DE experience I have ever had between windows, mac, and any linux DE. Amazing upgrade, don’t even need to upgrade my laptop now as my work flow is running smoother 4 years later than on day 1.

    Thanks team

  50. I’m so excited to become more active in the Fedora community than I’ve been in the past since I first started using the OS, but I’m even more excited that a new release is coming out right at the same time that I’ve decided to become a contributor as well. I can’t wait to be more involved!
