The macOS disk image runs on both Apple silicon and Intel. Windows and Linux need the build matching your processor.

On Linux, prefer a repository over a single file so Fluxer updates with the rest of your system.

## Linux package repositories

The package is `fluxer` for stable and `fluxer-canary` for canary. apt and dnf subscribe to one channel per entry file. pacman and Flatpak serve both from one repository.

### Flatpak

Fluxer's own Flatpak repository gets every update the day we release it. Open [the stable][flatpak-ref] or [the canary][flatpak-canary-ref] reference file and your software manager takes over. Some desktops also accept `flatpak+https://pkgs.fluxer.com/flatpak/fluxer.flatpakref` in the address bar.

From a terminal:

```sh
flatpak install https://pkgs.fluxer.com/flatpak/fluxer.flatpakref
```

Stable is also on [Flathub][flathub], but Flathub can be a few weeks behind and has no canary:

```sh
flatpak install flathub app.fluxer.Fluxer
```

### Debian and Ubuntu

```sh
sudo install -d -m 0755 /etc/apt/keyrings
sudo curl -fsSL -o /etc/apt/keyrings/fluxer-archive-keyring.gpg https://pkgs.fluxer.com/keys/fluxer-archive-keyring.gpg
sudo curl -fsSL -o /etc/apt/sources.list.d/fluxer.sources https://pkgs.fluxer.com/deb/fluxer.sources
sudo apt update && sudo apt install fluxer
```

For canary, use the canary entry file and package.

```sh
sudo curl -fsSL -o /etc/apt/sources.list.d/fluxer-canary.sources https://pkgs.fluxer.com/deb/fluxer-canary.sources
sudo apt update && sudo apt install fluxer-canary
```

A `.deb` installed from a download only updates once its channel's entry is added.

### Fedora and RHEL

```sh
sudo curl -fsSL -o /etc/yum.repos.d/fluxer.repo https://pkgs.fluxer.com/rpm/fluxer.repo
sudo dnf install fluxer
```

For canary, use the canary entry file and package.

```sh
sudo curl -fsSL -o /etc/yum.repos.d/fluxer-canary.repo https://pkgs.fluxer.com/rpm/fluxer-canary.repo
sudo dnf install fluxer-canary
```

RHEL, Rocky, Alma and CentOS Stream need `sudo dnf install epel-release` first, because their base repositories lack `libXScrnSaver`. Fedora does not.

### Arch Linux

The repository is signed, so pacman needs the key once:

```sh
sudo pacman-key --init
curl -fsSL -o /tmp/fluxer-archive-keyring.asc https://pkgs.fluxer.com/keys/fluxer-archive-keyring.asc
sudo pacman-key --add /tmp/fluxer-archive-keyring.asc
sudo pacman-key --lsign-key 09D01339EE128925F75E675C855C5BDE34D205D2
```

`--lsign-key` is what makes pacman trust it. Then add the repository:

```sh
sudo tee -a /etc/pacman.conf >/dev/null <<'REPO'

[fluxer]
SigLevel = Required TrustedOnly
Server = https://pkgs.fluxer.com/arch/$repo/os/$arch
REPO
sudo pacman -Syu fluxer
```

Write `$repo` and `$arch` literally. Both are pacman variables, not shell ones, hence the quoted heredoc.

Full setup notes, including canary, are in the [Linux repositories documentation][docs-linux].
