 <note>The X2Go TCE has been developed on/for Debian GNU/Linux. -- You can surely use any GNU/Linux distribution as X2Go Server (providing that the ''x2goserver'' package is available for the server's distro). The boot environment for the X2Go PXE Server has been developed on Debian GNU/Linux and also been tested on Ubuntu GNU/Linux. The X2Go Thin Client chroot can be configured to use Ubuntu GNU/Linux, but it is __highly recommended__ to leave the defaults and use Debian GNU/Linux for creating the X2Go TCE chroot.</note>

+If this command fails, please check if packages have been removed from your Debian version or if they are not yet available for your version. Also scan for other firmware packages:<code>
+$ apt-cache search firmware
