Default Dashboard not showing any data - possible elasticsearch startup problem

I have a new Ubuntu VM and I am trying to follow the get started instructions https://chaoss.github.io/grimoirelab-tutorial/docs/getting-started/setup/.
I have set the virtual memory ,and verified it. My machine as 8 CPUS, 16GB of memory.
I am using the default docker-compose method. I see the panels but no data.
When I browse port 9200 I get the following json response:
{
"name": "9PS5HiZ",
"cluster_name": "docker-cluster",
"cluster_uuid": "SOa1jgmoRea1bM0SGsQJ9g",
"version": {

"build_type": "docker",

},
"tagline": "You Know, for Search"
}

I have attached a copy of my terminal session in which you will see a clean git clone and command sudo docker-compose up , in case that helps.

Any ideas or suggestions to help get the default dashboard up would be appreciated.
I have tried multiple things like adding github and gitlab keys, but I have been informed that should not be necessary to see something. At the moment I only see panels with "no results found"

Start with the getting-started setup instructions and the attached terminal session, then inspect the docker-compose startup output and the Elasticsearch response on port 9200. Trace whether the default setup is ingesting data and identify why the dashboard panels report no results; done means a clean setup produces visible dashboard data without extra credentials.
