apt-get update Rootless Docker

  apt-get, docker, rootless, unattended-upgrade, updates

Installing Rootful Docker on my Raspberry Pi updates the sources and one can configure unattended-upgrades to update Docker automatically by looking at sudo apt-cache policy.

However, Rootless Docker doesn’t. So is there a way to upgrade Rootless Docker ?

In other words:

With Rootful Docker, sudo apt-get update && sudo apt-get -y upgrade on the host could upgrade the Docker installation. I would like to be able to do something similar with Rootless Docker.
Is it possible ?

To clarify: I am not trying to update the containers, but Docker itself.

Thanks in advance for any help you can provide 🙂
