ublue-custom  

These are customizations of upstream Universal Blue images, which themselves are customizations of Fedora CoreOS.

Installation

Warning

This is an experimental feature, try at your own discretion. If you are not yet on an existing atomic Fedora installation, you will first need to install any existing ublue or atomic Fedora image normally (e.g. via ISO on bare metal). Once installed, you can use that installation to complete the steps below.

To rebase an existing atomic Fedora installation to this build, including any ublue-based installation:

• First rebase to the unsigned image, to get the proper signing keys and policies installed:

  rpm-ostree rebase ostree-unverified-registry:ghcr.io/badbl0cks/bazzite-gnome-badblocks:latest
  

• Reboot to complete the rebase:

  systemctl reboot
  

• Then rebase to the signed image, like so:

  rpm-ostree rebase ostree-image-signed:docker://ghcr.io/badbl0cks/bazzite-gnome-badblocks:latest
  

• Reboot again to complete the installation

  systemctl reboot
  

Images

Currently the following images are available:

• bazzite-gnome-badblocks (Desktop gaming)
• ucore-hci-badblocks (Server/NAS-oriented)

Verification

These images are signed with Sigstore's cosign. You can verify the signature by downloading the cosign.pub file from this repo and running the following command:

cosign verify --key cosign.pub ghcr.io/badbl0cks/ublue
