[Koha] New install

[Сычев Игорь Алексеевич]

Hello Koha Community!

Why does the problem occur on a fresh install?
21.11
Unimarc

DBD::mysql::db do failed: Cannot add or update a child row: a foreign key constraint fails (koha_koha3.repeatable_holidays, CONSTRAINT repeatable_holidays_ibfk_1 FOREIGN KEY (branchcode) REFERENCES branches (branchcode) ON DELETE CASCADE ON UPDATE CASCADE) at /usr/share/koha/lib/C4/Installer.pm line 574.

Good Luck!
