Bluefin LTS#
Long-term support Bluefin stream built on CentOS Stream 10.
# LTS — recommended
sudo bootc switch ghcr.io/projectbluefin/bluefin-lts:stable --enforce-container-sigpolicy
# LTS — NVIDIA
sudo bootc switch ghcr.io/projectbluefin/bluefin-lts-nvidia:stable --enforce-container-sigpolicy
Migrating from ublue-os/bluefin-lts#
Users on the previous ghcr.io/ublue-os/bluefin*:lts images will be migrated automatically via a systemd service shipped in the weekly build. No action required — your machine will switch on its next reboot after pulling the update.
| Old image (ublue-os) | New image (projectbluefin) |
|---|---|
bluefin:lts | bluefin-lts:stable |
bluefin:lts-hwe (legacy tag) | bluefin-lts:stable |
bluefin-dx:lts | bluefin-lts:stable + run ujust devmode after reboot |
bluefin-dx:lts-hwe (legacy tag) | bluefin-lts:stable + run ujust devmode after reboot |
bluefin-gdx:lts | bluefin-lts-nvidia:stable + run ujust devmode after reboot |
| arm64 variants | No automatic migration — reinstall from new image |
To migrate manually before the automatic migration ships:
sudo bootc switch ghcr.io/projectbluefin/bluefin-lts:stable --enforce-container-sigpolicy
Getting Started#
Visit projectbluefin.io to download Bluefin LTS, or check the LTS Documentation for installation and upgrade instructions.
Rebasing between the Bluefin (Fedora) and Bluefin LTS (CentOS) image families is not supported. Plan migrations as fresh installs or supported upgrade paths.
