We have set up one mender server and one mender client, both on Debian 9 on AWS.

When I deploy I notice the error below:

2020-03-04 10:46:08 +0000 UTC error: Fetching Artifact headers failed: installer: failed to read Artifact: readHeaderV3: handleHeaderReads: Cannot load handler for unknown Payload type ‘docker-compose’

The artifact is below:

Mender artifact:

Signature: no signature

I am very beginner with all this, so any help is much appreciated.

Are you trying to deploy a file? Then you should probably use the `single-file` Update Module, which is available [here](https://hub.mender.io/t/single-file/486). The article tells you how to install it and use it.

The message you are getting is because there is no Update Module with the name “docker-compose”. I believe this message has been improved in the 2.2.0 client, which is just around the corner.
