Since a requirement on otopi >= 1.3.2 is in place, without a yum update ovirt-engine-3.6.0 can be installed with otopi-1.3.2 failing the setup with: [ ERROR ] Failed to execute stage 'Environment setup': type object 'BaseEnv' has no attribute 'EXIT_CODE' otopi-1.4.0 is required. Detected by jenkins: http://jenkins.ovirt.org/job/ovirt-engine_master_upgrade-from-master_el7_merged/518/console Not marking as blocker since 'yum update "otopi*"' solve the issue.
oVirt 3.6.0 has been released on November 4th, 2015 and should fix this issue. If problems still persist, please open a new BZ and reference this one.
