rebase command on bluefin website fails

[hanscees]

hi,
on this website
https://universal-blue.org/images/bluefin/

it is described howto rebase from a fedora silverblue install. However this fails

sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/ublue-os/bluefin:38

gives error : Fetchong manifest: containers-policy.json specifies a default of insecureAcceptAnything refusing image

anybody know howto fix this?

To be able to rebase to the signed images you will need to run sudo rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/bluefin:38 then use just enroll-secure-boot-key then you should be able to rebase to the sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/ublue-os/bluefin:38
