While upgrading my database, I get the following error: Updating database structure Update errors : Upgrade to 21.12.00.016 [13:43:24]: Bug 30060 - Update user_permissions to add primary key and remove null option from code column ERROR: {UNKNOWN}: DBI Exception: DBD::mysql::db do failed: Duplicate column name 'temp' at /usr/share/koha/lib/C4/Installer.pm line 739
Hi Keith, I believe this error was caused by an unifinished database update, so something that now needs a local fix and cannot be fixed in Koha itself. Have a look at bug 30912 too that dealt with a problem in this database update.
