BlueVanilla

A Fedora Silverblue image that uses vanilla GNOME and FlatHub apps.

Usage

1. Rebase to an unsigned image to get proper signing keys:

   rpm-ostree rebase ostree-unverified-registry:ghcr.io/aguslr/bluevanilla:latest && systemctl reboot
   

2. Rebase to a signed image to finish the installation:

   rpm-ostree rebase ostree-image-signed:docker://ghcr.io/aguslr/bluevanilla:latest && systemctl reboot
   

Alternatively, an ISO file for offline installation can be generated with the following command:

sudo podman run --rm --privileged --volume .:/isogenerator/output \
    --security-opt label=disable --pull=newer \
    -e IMAGE_REPO="ghcr.io/aguslr" -e IMAGE_NAME="bluevanilla" \
    -e IMAGE_TAG="latest" -e VARIANT="Silverblue" \
    ghcr.io/ublue-os/isogenerator:39
