This is only for the none GUI Hydra, I don’t have a GUI in my box did not care for it.
It should also work on older Ubuntu.

sudo apt-get update
sudo apt-get install libssh-dev libidn11-dev libpcre3-dev libsvn-dev libfbclient2
wget http://freeworld.thc.org/releases/hydra-6.2-src.tar.gz
tar -zxvf hydra-6.2-src.tar.gz
cd hydra-6.2-src
./configure
make
make install

During the make install it will complain about GTK, this is a non GUI install so ignore the errors.

Your done! to run type:
hydra
