I'm trying to copy the geolocation .sql file into my osclass database in mysql terminal but getting an error. Help is much appreciated.

MariaDB [osclassdb]> source /var/www/osc/kenya.sql;
ERROR 1451 (23000) at line 1 in file: '/var/www/osc/kenya.sql': Cannot delete or update a parent row: a foreign key constraint fails (`osclassdb`.`oc_t_city`, CONSTRAINT `oc_t_city_ibfk_2` FOREIGN KEY (`fk_c_country_code`) REFERENCES `oc_t_country` (`pk_c_code`))

You having block by foreign keys here. If your location tables are empty, you may want to first load country, then regions and last cities.
