Not enough entropy - raspberry pi3

I've installed freenet on a raspberry pi3 but have been unable to get it 
to start:

I have rng-tools installed and added HRNGDEVICE=/dev/urandom  to 
/etc/default/rng-tools  to no avail.


If found this command and I guess it tells me how much I have? Not sure, 
but I included it just in case it helps.

cat /proc/sys/kernel/random/entropy_avail 3116
