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

Stable is on [Flathub][flathub], the easiest route on most desktops:

flatpak install flathub app.fluxer.Fluxer

Flathub has stable only. To use Fluxer's own repository, 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:

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

Debian and Ubuntu

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.

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

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.

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:

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:

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].
