How to Upgrade MaxMind Location Database for Mint Pepper Location+

I just got the answer from the author’s email reply, thank you, Till:

$ wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
$ gunzip GeoLiteCity.dat.gz
$ mv GeoLiteCity.dat database.dat

Or you can just use this script to convert a CSV to DAT format
