Hi, I believe it's probably the same error here: *Bug 32762* <https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=32762> - Duplicate entry '10434' for key 'PRIMARY' at /usr/share/koha/lib/C4/Installer.pm line 739 Unfortunately, I doesn't have a fix or solution yet. Hope that helps, Katrin On 20.02.23 01:16, zen zenitram wrote:

Good morning all, we are trying to upgrade our koha database but too many duplicate entry shows.

ERROR - {UNKNOWN}: DBI Exception: DBD::mysql::db do failed: Duplicate entry 'ar' for key 'PRIMARY' at /usr/share/koha/lib/C4/Installer.pm line 739

This is the first error i encountered when upgrading koha from v20.05 to the latest version that is 22.11 and i already found the fix.

The next error is " ERROR - {UNKNOWN}: DBI Exception: DBD::mysql::db do failed: Duplicate entry '20534' for key 'import_biblios.PRIMARY' at /usr/share/koha/lib/C4/Installer.pm line 739".

we tried to locate this duplicate entry and it points to biblios in reservoir entry.

Anyone of you encountered this kind of error while upgrading?

I need help on how we gonna fix it.

Thank you! _______________________________________________
