I am working on a challenge on my Trailhead Playground, and when I click the verify step on the work done I get an error: 
The first time I tried to verify the challenge I got this error:
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: IBIDSYLA
The second time I tried to verify the challenge I got a different error:

Unable to install Data Quality Analysis Dashboards app from AppExchange to complete Trailhead challenge.  After reviewing instruction and troubleshooting videos, I still get the error.  I verified that the username was the one for my Trailhead Playground. I have used the link to the AppExchange app from the challenge, as well as going to the AppEchange dropdown from the Trailhead. I get to the install in production step and then the error occurs.
This app can't be installed.
There are problems that prevent this package from being installed.
