[Sofer Athlan-Guyot]

Hi,

this happen during run with tripleo upgrade under infrared:

TASK [Eanble validations] *******************************************************************************************************************************fatal: [undercloud-0]: FAILED! => {"msg": "The conditional check 'install.updates.validations' failed. The error was: error while evaluating conditional (install.updates.validations): 'dict object' has no attribute 'validations'\n\nThe error appears to be in '/root/infrared/plugins/tripleo-upgrade/infrared_plugin/main.yml': line 230, column 11, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: Eanble validations\n ^ here\n"}

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/tripleo-upgrade 8.0.0 release.
