Dear sir/madam We have installed Koha in 16.04 Ubuntu using package method. The koha version installed is 18.05.02.000. mysql Ver 15.1 Distrib 10.0.36-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2. We have come across the problem: Data problems Some of your tables have problems with their auto_increment values which may lead to data loss. *You should not ignore this warning.* The problem is that InnoDB does not keep auto_increment across SQL server restarts (it is only set in memory). So on server startup the auto_increment values are set to max(table.id)+1. To know how to avoid this problem see the related wiki page: DBMS auto increment fix <https://wiki.koha-community.org/wiki/DBMS_auto_increment_fix> Problems found Items The following ids exist in both tables *items* and *deleteditems*: 102358 -- Best regards Dr. Shankar Reddy Kolle
