Hi,
Try replacing lines 6 - 9 of "public/upgrade/templates/db_migration/1_7_pastafrola.php"
INSERT INTO `<?php echo $table_prefix ?>file_types` (`extension`, `icon`, `is_searchable`, `is_image`) VALUES
('slim', 'ppt.png', 1, 0),
('html', 'html.png', 1, 0),
('webfile', 'webfile.png', 0, 0);
with these ones:
INSERT INTO `<?php echo $table_prefix ?>file_types` (`extension`, `icon`, `is_searchable`, `is_image`) VALUES
('slim', 'ppt.png', 1, 0),
('html', 'html.png', 1, 0),
('webfile', 'webfile.png', 0, 0)
ON DUPLICATE KEY UPDATE id=id;
this will prevent that failure when insterting a row that already exists.
