I was helping some people do-release-upgrade from Ubuntu 18.04, to 22.04 and their koha was updated as well. I believe the previous version was 21.05.05-3. We upgraded the OS on the machine to 20.04, then to 22.04, and then upgraded Koha to 24.11.00-1. During the package configuration (repeatable by doing: dpkg --configure koha-common) we get the following response and error: root@elearning:/var/log# dpkg --configure koha-common Setting up koha-common (24.11.00-1) ... Upgrading database schema for opac Can't use string ("0E0") as a HASH ref while "strict refs" in use at /usr/share/koha/lib/C4/Installer.pm line 757. dpkg: error processing package koha-common (--configure): installed koha-common package post-installation script subprocess returned error exit status 255 Errors were encountered while processing: koha-common I tried looking through the log files to see if there was an "install log," but I did not see one. The code looks like it is applying individual updates schema, and one of them is failing. I am not sure how to figure out which one is failing, to then figure out why.
