I've downloaded the grr_master.zip from the Google page. But a more convenient way is to just
And run the install script after that. Please note that you need a working Internet connection and a bash shell.
/opt/grr-master/scripts# bash ./install_script_ubuntu.sh
Just follow the instructions on the screen. (Basically answering "Y" at any prompt and defining some mail addresses to use)
I had issues using Ubuntu Server 14.10, but after installing a fresh setup of Ubuntu Desktop 14.03, everything went fine.
After the install script has completed, generate the several keys need to sign communicaton and packets:
sudo grr_config_updater generate_keys
Add a user:
sudo grr_config_updater add_user joe
