I am running Koha on Debian 10 X64. Database is mariadb. When I attempt to perform the most recent routine update of koha-common via the apt package manager, the upgrade fails during the upgrade of the Koha database schema for my library database. Below is the verbose output of the installation failure. ------------ snip ----------------------------------- Upgrading database schema for library Upgrade to 20.06.00.000 done [11:18:06]: All our codebase are belong to everybody Upgrade to 20.06.00.001 done [11:18:06]: Bug 24986 - Switch borrowers address related fields to TINYTEXT or MEDIUMTEXT Upgrade to 20.06.00.002 done [11:18:06]: Bug 25184 - Items with a negative notforloan status should not be captured for holds Upgrade to 20.06.00.003 done [11:18:06]: Bug 24156 - Add new table tables_settings Upgrade to 20.06.00.004 done [11:18:07]: Bug 25851 - Remove holdallowed rule if value is an empty string Upgrade to 20.06.00.005 done [11:18:07]: Bug 24379 - Set login_attempts NOT NULL Upgrade to 20.06.00.006 done [11:18:09]: Bug 24151 - Add pseudonymized_transactions tables and sysprefs for Pseudonymization Upgrade to 20.06.00.007 done [11:18:09]: Bug 22844 - Add borrower_attribute_types.mandatory Upgrade to 20.06.00.008 done [11:18:09]: Bug 23148 - Replace Bridge icons with transparent PNG files Upgrade to 20.06.00.009 done [11:18:10]: Bug 23391 - Hide finished ILL requests Upgrade to 20.06.00.010 done [11:18:10]: Bug 20815 - Add NoRefundOnLostReturnedItemsAge system preference Upgrade to 20.06.00.011 done [11:18:10]: Bug 5087 - Add export_format.staff_only Upgrade to 20.06.00.012 done [11:18:10]: Bug 23795 - Convert OpacCredits system preference to news block Upgrade to 20.06.00.013 done [11:18:10]: Bug 23795 - Convert OpacCustomSearch system preference to news block Upgrade to 20.06.00.014 done [11:18:10]: Bug 23797 - Extend the opac_news lang column to accommodate longer values Upgrade to 20.06.00.015 done [11:18:10]: Bug 23797 - Convert OpacLoginInstructions system preference to news block Upgrade to 20.06.00.016 done [11:18:11]: Bug 23092 - Add 'daterequested' field to transfers table Upgrade to 20.06.00.017 done [11:18:11]: Bug 25709 - Rename systempreference to NotesToHide Upgrade to 20.06.00.018 done [11:18:11]: Bug 24157 - Add new permissions reopen_closed_invoices, edit_invoices, delete_invoices, merge_invoices, delete_basket Upgrade to 20.06.00.019 done [11:18:11]: Bug 22660 - Adds NewsToolEditor system preference Upgrade to 20.06.00.020 done [11:18:11]: Bug 26070 - Remove references to deprecated Google Transliterate API Upgrade to 20.06.00.021 done [11:18:11]: Bug 25871 - Add library option to OpacItemLocation Upgrade to 20.06.00.022 done [11:18:17]: Bug 21946 - Add parent type to itemtypes Configuration not defined at /usr/share/perl5/Log/Log4perl/Config.pm line 579. dpkg: error processing package koha-common (--configure): installed koha-common package post-installation script subprocess returned error exit status 11 Errors were encountered while processing: koha-common E: Sub-process /usr/bin/dpkg returned an error code (1) ---------- snip end ----------------------------- I have not been able to figure out where this failure is actually occurring, but it seems to be a problem with the database structure. Any help would be greatly appreciated. Scott
