Title:
  Fail to configure a Centos 8 machine with cloudlinux

Status in cloud-init:
  Expired

Bug description:
  Hi.

  We use cloud-init to boot our hosting servers in an ovirt/RHEV
  environment. While the integration with a plain CentOS 8 works fine,
  cloud-init fails with an error on a CentOS 8 machine converted to
  cloudlinux.

  Both the machines are derived from the same base image. Here the
  output (some informations are redacted for privacy reasons):
