Hi there, I'm trying to setup Koha 20.11 on my Ubuntu 20.04 LTS server. I followed the steps in Koha on ubuntu - packages page (https://wiki.koha-community.org/wiki/Koha_on_ubuntu_-_packages#Appendix_A:_N...). I installed MySQL server instead of MariaDB. I can visit the administration website to continue with the Koha web installer. I can login with the given username and password. The succeeding setup steps are fine. But when I get to the step "Now we're ready to create the database tables and fill them with some default data."...I am getting the following error and cannot further proceed with the setup. The following error occurred while importing the database structure: [Sun Apr 18 15:05:07 2021] install.pl: DBD::mysql::st execute failed: Cannot drop table 'auth_types' referenced by a foreign key constraint 'auth_subfield_structure_ibfk_1' on table 'auth_subfield_structure'. at /usr/share/perl5/DBIx/RunSQL.pm line 279, <$args{...}> line 1.

Please contact your system administrator Any idea how I can resolve this? Thank you very much for your assistance.
