[ovirt-users] Upgrade 4.2.8 to 4.3.1 failed: Constraint violation found in vm_interface (vmt_guid) |1

I tried to upgrade my engine and was running engine-setup when: [ INFO  ] Checking the Engine database consistency [ ERROR ] Failed to execute stage 'Setup validation': Failed checking Engine database: an exception occurred while validating the Engine database, please check the logs for getting more info:          Constraint violation found in  vm_interface (vmt_guid) |1 I found https://bugzilla.redhat.com/show_bug.cgi?id=1528316 but that looks to have been resolved already. How should I proceed?
