Fluxer

Fluxer is a free and open source instant messaging and VoIP chat app built for friends, groups, and communities.

The macOS disk image is universal and runs on both Apple silicon and Intel. Windows and Linux need the build that matches your processor.

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

All four repositories serve stable and canary. The package is fluxer for stable and fluxer-canary for canary.

Opening this reference file hands the install to your desktop software manager. Some desktops also accept flatpak+https://pkgs.fluxer.com/flatpak/fluxer.flatpakref pasted into the address bar.

From a terminal:

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

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

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

RHEL, Rocky, Alma and CentOS Stream need sudo dnf install epel-release first, because the base repositories do not ship libXScrnSaver. Fedora does not need this.

The repository is signed, so pacman needs the key in its own keyring 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 the step that makes pacman trust the key. 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, which is why the heredoc above is quoted.
