Seems like multiple gerrits for multicloud-k8s are failing now.  One common failure is in the multicloud-k8s-master-kud-deployment-verify-shell job.

A couple example gerrits with this issue are:

https://gerrit.onap.org/r/c/multicloud/k8s/+/107497

https://gerrit.onap.org/r/c/multicloud/k8s/+/107922

The error seen in the log is:
