Hi, Unfortunately we have just found that latest release of postgresql-jdbc-42.2.14-1 breaks existing oVirt Engine 4.4 and 4.5 installations running on CentOS Stream. The workaround is to downgrade to previous version, for example postgresql-jdbc-42.2.3-3 should work fine. Here are detailed instructions: 1. If you have already upgraded to postgresql-jdbc-42.2.14-1, please downgrade to previous version: $ dnf downgrade postgresql-jdbc $ systemctl restart ovirt-engine 2. If you are going to upgrade your oVirt Engine machine, please exclude postgresql-jdbc package from upgrades: $ dnf update -x postgresql-jdbc We have created https://bugzilla.redhat.com/2077794 to track this issue, but unfortunately we don't have a fix yet.
