[Koha] KOHA DOWNGRADE

Dear Community Does anyone know how to move from codename release Koha, to version number. When our Koha was installed it was initially put on codename and this automatically updates our koha to a newer version. Thus, we would like to make it stop, and stay on that version of Koha until the package sources are changed. Please advise where to change to stop the automatic update of koha. *We are currently on:* *Koha oldoldstable* (23.05) Regards, Russel Shihepo Notitia Systems Namibia
