Install the FAHClient.
sudo dpkg -i --force-depends fahclient_7.4.4_amd64.deb

sudo dpkg -i --force-depends fahcontrol_7.4.4-1_all.deb
Optionally, install the FAHViewer.
sudo dpkg -i --force-depends fahviewer_7.4.4_amd64.deb
Done. The FAHClient is installed and running as a service. Manage, monitor and update settings using the FAHControl.
