Installation

Warning This is an experimental feature and should not be used in production!

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

  sudo rpm-ostree rebase ostree-unverified-registry:ghcr.io/scottames/ublue:latest
  

• Reboot to complete the rebase:

  systemctl reboot
  

• Then rebase to the signed image, like so:

  sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/scottames/ublue:latest
  

• Reboot again to complete the installation

  systemctl reboot

git rebase upstream/template
# resolve any conflicts
git push

# Rebase your own "live" changes onto the latest template.
git checkout live
git rebase --onto live template

# Perform a force-push to update your "live" branch on GitHub, to deploy.

# is different than your local version (ie. if a team member pushed to it).
