"No polkit authentication agent found" error in GNU/Linux
----------------------------------------------------------
Etcher requires an available [polkit authentication
agent](https://wiki.archlinux.org/index.php/Polkit#Authentication_agents) in
your system in order to show a secure password prompt dialog to perform
elevation. Make sure you have one installed for the desktop environment of your
choice.
