Comment 2 for bug 1536267

The same error for job https://packaging-ci.infra.mirantis.net/job/8.0-pkg-systest-ubuntu/1954/

Also I have meet this error in little different view here:
https://packaging-ci.infra.mirantis.net/job/8.0-pkg-systest-ubuntu/1953/

In the second case error looks like:

  fuel-rabbit-fence
Authentication warning overridden.
