Sunny day all! First time I have this problem: I'm trying to upgrade a 17.05 to 24.11, but it keeps failing on constraints Upgrade to 17.12.00.015 done (Bug 20144 - Adapt DB structure to work with new SQL modes) {UNKNOWN}: DBI Exception: DBD::mysql::db do failed: Cannot change column 'type': used in a foreign key constraint 'koha_henryville/account_offsets_ibfk_t' of table 'koha_henryville/account_offsets' at /usr/share/perl5/DBIx/Class/Schema.pm line 1118. DBIx::Class::Schema::throw_exception(Koha::Schema=HASH(0x5e4975bc04e8), "DBI Exception: DBD::mysql::db do failed: Cannot change column"...) called at /usr/share/perl5/DBIx/Class/Storage.pm line 113 DBIx::Class::Storage::throw_exception(DBIx::Class::Storage::DBI::mysql=HASH(0x5e497aefac50), "DBI Exception: DBD::mysql::db do failed: Cannot change column"...) called at /usr/share/perl5/DBIx/Class/Storage/DBI.pm line 1623 DBIx::Class::Storage::DBI::__ANON__("DBD::mysql::db do failed: Cannot change column 'type': used i"..., DBI::db=HASH(0x5e497b75b710), undef) called at ./installer/data/mysql/updatedatabase.pl line 15545 This was an install on Debian 12 / Mariadb 10.11 with the koha-common packages, so I figured maybe some new constraints in Mariadb were in cause. I moved the DB to a Ubuntu 22, Mariadb 10.6 with dev install but I have the same problem. I've never encountered it in my upgrades up to 24.05, and there's no way to skip it since it's a loop through ALL the tables to add the COLLATE, etc... And the code starts with skipping the constraints, so I don't get it. Any suggestion?
