Getting Ultramarine Linux

System Requirements

If your computer could run Windows 7 well, chances are it’ll run Ultramarine Linux. You should check the System Requirements to make sure

Choosing Your Edition

Ultramarine Linux comes in 4 variants:

  • Flagship Edition: Our default and most popular variant. Choose Flagship if you’d like a familiar and stylish experience.
  • KDE Edition: Our second most popular variant. Choose KDE if you’d like a simply customisable experience.
  • GNOME Edition: Elegant and Modern. Choose GNOME if you’d like a simple, unique experience.
  • Xfce Edition: Lightweight and Configurable. Choose Xfce if you’d like a lighter experience.

Check the System Requirements to make sure your hardware is supported.

Ultramarine Linux is distributed in various formats available for download from our website.

Fyra Labs cannot guarantee the safety or quality of images downloaded from sites other than our website or FOSSTorrents

Atomic

Ultramarine Linux also comes in Atomic versions. Ultramarine Atomic works similarly to Fedora Silverblue, CoreOS, and other OSTree-based operating systems. This variant is made for users who want a stable, immutable system that is easy to recover from. We see immutability as the future of Linux systems. Ideally, this will become the standard edition in the future.

These builds are currently in beta. If you are planning to test them, please join our Discord or Matrix community first and let us know. We’ll be happy to receive feedback and assist you.

Raw Images and Raspberry Pi

Ultramarine is also availible as a raw (or preinstalled) image. These images come with a desktop preinstalled and are intended to be flashed directly to the drive your device will boot from (like an SSD or an SD card.)

These can be found in the Raw Image sections of the download page.

Ultramarine images have a matching checksum file that can be checked against the image itself.

They can be downloaded by clicking the View checksum button on the download page.

Verifying the Checksum on Linux and macOS

You can use the following commands to check the integrity of the image:

sha256sum -b /path/to/ultramarine.iso # Generate the checksum for the image
cat /path/to/checksum # Check the checksum

# Now you can compare the checksum

Verifying the Checksum on Windows

In Powershell, run this command:

CertUtil -hashfile PATH\TO\ULTRAMARINE.ISO SHA256
# Open the checksum file with Notepad and compare the checksum

If you’re using a Raspberry Pi, stop here and go to the Raspberry Pi instructions

Creating the Installer

Grab a USB stick! Use a flasher program to create an installer from the image. balenaEtcher is an easy cross-platform choice.

You can also use Fedora Media Writer, or the Disks application on Flagship, Xfce, and GNOME editions.

Rufus has been known to cause issues with Ultramarine images.

Booting the Installer

After flashing the image to your installer, you can boot to Ultramarine Linux by plugging in the installer and restarting your computer.

Most computers have a special key that can be used to select a boot device, or to enter the setup screen. This varies from brand to brand, check the BIOS Keys Page for how to enter the boot menu on your machine.

If you’re currently using Windows 10 (or newer) head to the recovery section of settings and select “Advanced Restart”. Once there, select “Use a Device”.

If you’re currently using Linux, you may be able to enter the BIOS by running sudo systemctl reboot --firmware

Footnotes

  • The Anaconda installer is very complex and hard to work with, we are working on a new installer that is easier to use and more reliable.
  • Since Fedora 37 the Ultramarine team has maintained Pantheon, in Ultramarine 40 we will be dropping Pantheon due to major issues with the experience.
  • Ultramarine’s Budgie edition provides a close to stock Budgie experience, with a custom theme. Unlike Fedora’s Budgie Spin, which provides a completely custom layout and experience.
