Duplicate constraints when creating mysql tables

[ScrumpyJack]

I get this when using mysql.initial.sql

ERROR 1005 (HY000) at line 113: Can't create tableroundcubemail.database_calendars(errno: 121 "Duplicate key on write or update")

Here are the foreign keys on my database

MariaDB [roundcubemail]> SELECT constraint_name, table_name FROM information_schema.table_constraints WHERE constraint_type = 'FOREIGN KEY' AND table_schema = DATABASE() ORDER BY constraint_name;

constraint_name	table_name

Looks like there already is a fk_calendars_user_id contraint

Got this working with SET FOREIGN_KEY_CHECKS=0; , deleting all the tables then reimporting the sql
