Hi, on my system using mysql I had the same error. Comment 34 for Bug 31086 https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=31086#c34 helps. It seems that KOHA with mariadb is better tested than KOHA with mysql. Is there a way to exchange the underlying database mysql by mariadb?

Hi All,
It seems like that for every other update I experience a DBI Exception in the update process. In the latest upgrade of 22.05.04-1 to 22.05.05-1 I have received the message:
Upgrade to 22.05.04.002 [14:33:32]: Bug 31086 - Do not allow null values in branchcodes for reserves ERROR - {UNKNOWN}: DBI Exception: DBD::mysql::db do failed: Cannot change column 'branchcode': used in a foreign key constraint 'reserves_ibfk_4' at /usr/share/koha/lib/C4/Installer.pm line 739
Indeed, there are null values for branchcodes in the reserves table as I do not have any courses or reserves in my system. Is there a fix for this error? I have included the console log below:
Thanks
