jobs running with "rdo-cloud" provider are broken, mainly jobs running on package update in RDO

The tripleo jobs in package update jobs in RDO fails with following Error too early:-

Jobs running with "rdo-cloud-tripleo" provider are passing, ex:-

Suspected change:- https://review.openstack.org/#/c/596432/48/toci_gate_test.sh@26

Only one provider("rdo-cloud") is affected, others (vexhost and rdo-cloud-tripleo) working fine. Still will add promotion-blocker tag it's affecting package updates, so we need to get this fixed.
