UBTU-16-010000 - The Ubuntu operating system must be a vendor supported release.
An Ubuntu operating system release is considered 'supported' if the vendor continues to provide security patches for the product. With an unsupported release, it will not be possible to resolve security issues discovered in the system software. NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Upgrade to a supported version of the Ubuntu operating system.
