Install failing on Ubuntu 18.04

[aseigler]

Clean OS install, had multiple people try, same results with 16.04. Spotted some earlier similar-ish looking issues related to GeoLite2 databases but I am seeing those files in the root of the /opt folder.

Everything looks good before this point, here's the end leading up to the failure.
