Guacamole Installation

These are supposed to be the only necessary steps to install Guacamole, but the add-repository step didn't work:

sudo add-apt-repository ppa:guacamole/stable
sudo apt-get install guacamole-tomcat

So, had to install from source. Installation of prerquisites:

sudo apt install libcairo2-dev
sudo apt install libjpeg-turbo8-dev
sudo apt install libpng-dev
sudo apt install libtool-bin
sudo apt install libossp-uuid-dev
