| Fedora Atomic Host installations use the [https://rpm-ostree.readthedocs.org/en/latest/ rpm-ostree deployment method], where packages are assembled on the Fedora release engineering side and delivered as atomic units, rather than the yum/DNF method of client side assembly. Consequently, they do not use the [[DNF system upgrade]] mechanism which is used to upgrade between Fedora releases for other Fedora installations. Instead, use the procedure described here. | | This article applies to Fedora Atomic Host (though there is also a [https://pagure.io/workstation-ostree-config/ Silverblue/Atomic Workstation]). For "classic" Fedora Workstation and Server, see [[DNF system upgrade]]. |

| {{admon/note|One OSTree repository per release|It's crucial to note that at the moment, Fedora uses separate OSTree repositories for each major release. This makes switching between versions more painful. For more information, see [https://fedorahosted.org/rel-eng/ticket/6125 this ticket].}}

| Let's assume you're upgrading from Fedora {{FedoraVersionNumber|previous}} to {{FedoraVersionNumber|current}}. First, you'll need to add a remote for the new major version:
| |
| | |
| ostree remote add fedora-{{FedoraVersionNumber|current}} --set=gpg-verify=false https://dl.fedoraproject.org/pub/fedora/linux/atomic/{{FedoraVersionNumber|current}}
| |
| | |
| Then, rebase to it:
| |
| | |
| rpm-ostree rebase fedora-{{FedoraVersionNumber|current}}:fedora-atomic/{{FedoraVersionNumber|current}}/x86_64/docker-host
| |
| | |
| Like any other rpm-ostree update, this is staged for the next reboot, so to finally apply the update:
| |
| | |
| systemctl reboot
| |
| | |
| That should be all!
