Hi, The following error message occurs when I import the data backed up from Maridb 10.5.22 Ubuntu 20.04 to Maridb 10.6.12 Ubuntu 22.04： root@koha2023:/home/koha# mysql -uroot koha_library < koha_library-12-10-2023-10.37.sql ERROR 1005 (HY000) at line 4373: Can't create table `koha_library`.`items` (errno: 150 "Foreign key constraint is incorrectly formed") Does anyone know how to solve this problem? Good Luck! Peter Zhao | | | | |
