We see the error as following:

resource_management.core.exceptions.Fail: Cannot match package for regexp name ranger_${stack_version}-admin.

.

So it looks like somehow ambari is not able to determine the "${stack_version}" for the ranger admin package.

So can you please check if you have something like this in your following two scripts:

# grep 'package_version = None' /usr/lib/ambari-server/lib/resource_management/libraries/script/script.py
    package_version = None
# grep 'package_version = None' /usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py
    package_version = None

.

On the host where ranger admin installation is failing, can you please try commenting the mentioned line starting with "package_version = None" and then retry from ambari UI to install ranger.

# package_version = None

.
