Before you install
Read the release notes and installation guide before downloading. Select an image that matches the processor architecture and intended use: desktop, server, live media, virtual machine or another published edition. Test Wi-Fi, graphics, audio, storage and suspend from live media when that option is available. Back up important files before repartitioning, encryption changes or dual-boot installation. Download from an official project page or mirror, compare the published SHA-256 checksum, and verify a signed checksum when the project provides one. After installation, apply updates before adding third-party repositories or drivers.
- 1Check the SHA-256
Compare the file with the checksum published by Ultramarine Linux. If it does not match, download it again.
- 2Write it to a USB drive
Use Ventoy, balenaEtcher, Fedora Media Writer or Rufus. Copying the ISO as a normal file does not work.
- 3Boot from the USB
Open the boot menu (often F12, F10 or Esc) and choose the USB drive in UEFI mode. Back up your data first.
About Ultramarine Linux
Ultramarine Linux is a Fedora-based desktop distribution with multimedia support, additional repositories and several preconfigured environments. Release 44 is offered in Plasma, GNOME, Xfce and Budgie editions. This catalogue entry selects the generic x86-64 Plasma live installer; specialized hardware images should be chosen through the official selector when required.
Who is it for?
Ultramarine Linux is primarily suited to daily desktop use, study, web browsing and productivity. Before choosing it, compare the current release lifecycle with the length of support required for the machine. This distribution is based on fedora, which influences package formats, repositories and much of the available documentation. The listed desktop environment is KDE Plasma; confirm its memory, graphics and accessibility requirements on the official project site. The best choice depends on hardware support, preferred software, update policy and the amount of system administration the user wants to perform.
