Is the latest Ubuntu 18.04 LTS image available on Docker Hub trusted/signed or not?

docker 18.04

Ubuntu Docker images are official images released directly by Canonical. And it's correct that the 26 Nov 2020 Ubuntu 18.04 LTS image is the most recent signed image.

It seems signed images are updated on a less regular basis than unsigned, so you have to choose either signed with DCT or latest - you can't have both.
