Hi Webmasto,
in this Jasmine Quickstart guide, the error is specifically located in the file:
installation/sql/mysql/custom.sql
The relevant line in your package is 2344:
INSERT INTO `#__user_usergroup_map` VALUES (...,(443,8),...);
The primary key of this table is (user_id, group_id), so if (443,8) already exists during import, Joomla throws the error:
Duplicate entry '443-8' for key 'PRIMARY'
A simple workaround is to change:
INSERT INTO `#__user_usergroup_map` VALUES (...,(443,8),...);
to:
INSERT IGNORE INTO `#__user_usergroup_map` VALUES (...,(443,8),...);
This way, duplicate mappings are skipped and the installation can continue.
Best regards
