Hello, I am new to Mender, and am attempting to setup Mender to support OS updates, application updates, and docker container updates. I will be using this on Ubuntu 18.04, 20.04, and 22.04, but my current test is using 22.04 and 20.04.

I setup my test boxes with the following partitions.  
1GB /boot  
10GB /  
10GB /secondary  
9G /data

I created a new Ubuntu 22.04 Server, and created a snapshot using mender-artifact, and I uploaded this package to the hosted Mender, as a release.

I added both a new separate Ubuntu 22.04 and 20.04 machine to devices through docker. I created a deployment for the two devices with the snapshot release. Following this step [Deploy an Operating System update | Mender documentation](https://docs.mender.io/get-started/deploy-an-operating-system-update#step-4-modify-the-device-software) I added the greetings file to both machines. The deployment finishes saying successful, however I see no actual changes on the two machines itself. The greetings.txt file still remains.

What step am I missing here? I have attempted this on multiple setups now and keep getting the same result. Will be happy to provide any helpful additional information.
