# Enable binary cache for faster installs
cachix use shini4i

# Install
nix profile install github:shini4i/nixpkgs#openfortivpn-gui

A NixOS module is also available for declarative configuration.

Fedora

Download the .rpm package from GitHub Releases:

sudo dnf install ./openfortivpn-gui-*.rpm

After installation, enable passwordless VPN operations:

sudo usermod -aG openfortivpn-gui $USER
# Log out and back in, then:
sudo systemctl enable --now openfortivpn-gui-helper
