I am trying this new Trail and receiving errors trying to install the package. I created a brand new playground for it, and then clicked the link. It told me:
This app can't be upgraded.
There are problems that prevent this package from being installed.
Unable to install.The unmanaged package "Trailhead Project" is already installed in your organization. You will need to uninstall it before installing a new version.
Trailhead Project is automatically created in a new playground, but the instruction makes it seem as if it's trying to install the DreamHouse app. Could this be an incorrect Link?

Uninstall the unmanaged package named as Trailhead Project. And try installing the package again from the trailhead.
Let me know if this resolves your issue.
