Hi,

we had a failure to deploy hosts for change; https://gerrit.ovirt.org/#/c/94228/1

I don't think its related directly to the change but anything between
packaging: use system provided nimbus-jose-jwt also on el7 patch and current patch could have caused the failure.

https://gerrit.ovirt.org/#/q/project:ovirt-engine+status:Merged+branch:master

Sandro, Ondra, can you please have a look?

(Relevant) error snippet from the log:
