Changes in: /usr/share/koha/intranet/cgi-bin/installer/data/mysql/db_revs/230501003.pl to convert publishercode to text on both tables resulted in an upgrade error. Manually deleted the indexes from the tables allowed the [Try again] to proceed without incident.
The error was something like: "column 'publishercode' used in key specification without a key length" Sorry I don't have the full output.
Actions I took: DROP INDEX `publishercode` ON `koha_instance`.`biblioitems` DROP INDEX `publishercode` ON `koha_instance`.`deletedbiblioitems`
