Hi, Could someone please provide advice on a production oVirt instance that fails to upgrade to 4.2.3? Engine and hosts are all running CentOS 7 As per the upgrade instructions in the release notes I run: # yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm # yum update "ovirt-*-setup*" # engine-setup Then I answer the questions and it fails with: ... [ INFO ] Upgrading PostgreSQL [ ERROR ] Failed to execute stage 'Misc configuration': Command '/opt/rh/rh-postgresql95/root/usr/bin/postgresql-setup' failed to execute [ INFO ] Yum Performing yum transaction rollback [ INFO ] Rolling back to the previous PostgreSQL instance (postgresql).

Can anyone offer any other suggestions?
