Hi Eugen, have a look at About Koha > System information. You'll probably see a note about duplicated IDs in your database and a link to this wiki page: https://wiki.koha-community.org/wiki/DBMS_auto_increment_fix Hope this helps, Katrin On 16.02.23 09:05, DHIM IT wrote:
Dear colleagues,
I have problem on one of koha instance Version 22.05.09.000.
If I try to delete some biblio, fresh created too, I get this error: An error has occurred! Error 500
From: /var/log/koha/koha/plack-error.log
{UNKNOWN}: DBI Exception: DBD::mysql::db do failed: Duplicate entry '61703-marcxml-MARC21' for key 'deletedbiblio_metadata_uniq_key' at /usr/share/koha/lib/C4/Biblio.pm line 2867
At the same time biblio landed in to the table deletedbiblio. After deleting of record from deletedbiblio and trying to delete the record again, it works.
Maybe have somebody idea about the error?
Mit besten Grüßen IT-Manager Eugen Bastron
