Unable to start on-premise demo server per "Getting Started" instructions

We're attempting to use Mender for a project. Tried following the demo steps outlined lead to no failures, however it does not function. As noted in environment, the below was tested on both Ubuntu 18.04 and Debian Stretch.

Following the instructions starting here: https://docs.mender.io/2.2/getting-started/on-premise-installation

I've installed the latest Docker Engine - Community and Docker Compose as linked to in the manual, that is, Docker CE 19.03 and Compose 1.25. Note that the specified version of Docker CE as 17.03 is not viable in Debian Stretch due to conflicts, and no longer exists in Ubuntu 18.04. Using Compose 1.6 causes some other runtime error when starting the demo script.

Using integration.git, 2.2.1, and starting the demo server, the following occurs:

Running './demo down' and './demo up' at this point repeats the same "Creating..." lines followed by the same "useradm" error. There is no web server running on localhost:80 or :443. And, while there appears something is running on :8080, it is not anything like the documentation describe it.

Attempting to view logs as outlined in the Troubleshooting section (https://docs.mender.io/2.2/troubleshooting/mender-server) results in no usable output:

$ ./demo --client logs mender-client}}

I've also found that the README in integration.git not only lists different Docker Engine and Docker Compose requirements, but also the Engine requirement of version "1.10" is not a Docker Engine - Community package and appears to be an older Docker Engine release.

I've verified all permissions, tested under both Ubuntu and Debian as I've said. I'm not sure what else I am missing at this point other than these instructions and/or the demo script are incorrect somehow. How exactly do I set up a viable demo server?
