## The issue

The version that is needed by the Supervisor, depends on the features it needs
for it to work properly.

The current minimum supported version of Docker is: `20.10.17`.

However, the feature set changes and improves over time and therefore, the minimal
required version may change in the future. When that happens, it will be communicated
before we publish a version that will require you to upgrade Docker.

## The solution

If you are running an older version of our Home Assistant OS, update it the
{% my configuration title="Configuration" %} panel.

If this is not our Home Assistant OS, you need to manually update Docker on your
host for instructions on how to do that, check the official
[Docker documentation](https://docs.docker.com/engine/install/debian/).
