Can you explain the benefits of creating Ubuntu versions in Docker vs using Ubuntu directly via the built in Github Workflow feature?

Hello @rnorris ,

As you can see, I did not find a solution to run build and tests directly on the native Ubuntu provided by Github. The last failure seems to be related to the repeated installation of dependencies.
As there is no reason to always download fresh dependencies packages all the time, I decided to give a try via a Docker ecosystem: creating Docker images and then, working inside these images.

Currently, it is a long try-failure loop...
