Yes, all the Koha data and settings were fine. It just was the Koha koha-common software that was uninstalled during MariaDB upgrade from 10.5 to 10.6 so I was able to get Koha back up quickly by installing koha-common using apt install koha-common Dwight Walker September 10, 2025 10:00 AM, koha-request@lists.katipo.co.nz wrote:

To clarify: was all your data and configuration preserved in this process? After re-installing the koha-common packages things were fine again?

Hi

When I was upgrading MariaDB 10.5 to 10.6 on Debian 11 Linux, I discovered Koha 22.05.22.000 was uninstalled in form of koha-common.

Koha was not there when I opened my OPAC URL.

The process of upgrading MariaDB included uninstalling 10.5 which was when Koha as koha-common was uninstalled.

After I installed MariaDB 10.6 I had a database but no Koha software.

Koha relies on MariaDB to hold the catalogue.

To get Koha software back, I reinstalled Koha software as root in command line interface (CLI) on Debian 11 Linux:

apt install koha-common
