First, you need to import the repository GnuPG key, if apt-key is available you can use these command as root:

apt-key adv --keyserver keyserver.ubuntu.com --recv 049ED9B94765572E

Otherwise this one will work:

wget -O - http://debian.fusioninventory.org/debian/archive.key | apt-key add -

Now you can install the agent.

apt-get install lsb-release
echo "deb http://debian.fusioninventory.org/debian/ `lsb_release -cs` main" >> /etc/apt/sources.list
apt-get update
apt-get install fusioninventory-agent

Note: On Debian Testing, you need to fix the /etc/apt/sources.list update so you use jessie repo. You can better replace the second line from the previous commands with:

echo "deb http://debian.fusioninventory.org/debian/ jessie main" >> /etc/apt/sources.list

The content of the dists pages can help you do identify support operating system.
