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, 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 or the canary 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.
