NVIDIA RTX 2060 --- ubuntu-drivers does not make suggestions

On a new installation of Ubuntu Desktop 18.04 LTS, with all package updates installed, running

  ubuntu-drivers list

produces no output. The system has an NVIDIA RTX 2060 card installed. The Ubuntu IRC support channel folks suggest this is an issue because ubuntu-drivers should make a suggestion, hence this report.
