# Alternate Installation

## General instructions

This guide is supported on a best effort basis, expect paper cuts!

If you have issues installing with the Aurora ISO and want to try rebasing from a Fedora Kinoite installation (**rebasing from Silverblue is NOT supported!**), this guide is for you. Rebasing will give you almost the same great experience as a fresh installation from our ISO, but there are some steps you need to follow.

1. Determine your image name. Select your desired Aurora Version in the ISO download screen on <a target="_blank" href="https://getaurora.dev">getaurora.dev</a> and note it down. You're gonna need it in the next steps.

2. Download Fedora Kinoite (**<a target="_blank" href="https://fedoraproject.org/atomic-desktops/kinoite/">from here</a>**) and install it when you don't have an existing installation. The process is very similar to the Aurora installation process. **_Do not create a root user._**

3. Once you are booted into your new or existing Kinoite installation, run the following command (substituting the placeholder with the image name you noted down earlier) and reboot afterwards:

```
sudo bootc switch ghcr.io/ublue-os/<imagename>
```

_For example: `sudo bootc switch ghcr.io/ublue-os/aurora-dx:stable`_

4. After you have rebased to Aurora, you need to rebase a second time. This time, to a signed version of the image so you have a verified and secure copy of the OS.

```
sudo bootc switch --enforce-container-sigpolicy ghcr.io/ublue-os/<imagename>
```

_For example: `sudo bootc switch --enforce-container-sigpolicy ghcr.io/ublue-os/aurora-dx:stable`_

5. Now that you are on Aurora, add Flathub:

```
flatpak remote-add --if-not-exists --system flathub https://flathub.org/repo/flathub.flatpakrepo
```

6. Download the Warehouse application with `flatpak install flathub io.github.flattool.Warehouse`, click on Packages -> Filter Packages -> Select All and uninstall them, after that you go to the Remotes tab and remove the Fedora Flatpak remote. This will not remove any application data.

7. After all of that is done, you can relax a bit. Now it's time for the last step, you will want to install our curated flatpaks to get the best out of your experience. Run the following command in your terminal:

```
ujust install-system-flatpaks
```

## Rebasing from an existing Fedora Kinoite Installation

First you might want to permanently save your current deployment:

```
sudo ostree admin pin 0
```

The following command will remove all changes you made with rpm-ostree, like layered packages and kernel parameters to ensure a successful rebase to Aurora.

```
rpm-ostree reset
```

After that you can start right from step 3 above.

## Rebasing from another Bootable Container Image (e.g. Bazzite)

If you want to rebase from a Bazzite-KDE Installation to Aurora, you can just skip steps 1-3 and grab a command with your desired image from step 4, from the installation guide above.

**Note**: Bazzite [blocklists](https://github.com/ublue-os/bazzite/blob/d67570f37329e20d26869648cfa759c10bfc667f/system_files/desktop/shared/usr/share/ublue-os/flatpak-blocklist) applications like Flatpak Steam, you will have to undo that with `flatpak remote-modify --system --no-filter flathub` on Aurora.

**Note:** Do not rebase from a Gnome-based image to Aurora or back!
