I think I might have found where the issue is: in the Quick Start Guide page, the git clone command for getting the meta-intel layer was missing the -b krogoth flag. So I got the master branch of that layer (instead of the Krogoth branch), which does not match with the rest of the layers.
After fixing that, I am able to start the build (it is building as I type).
Please update the Quick Start Guide page to correct this typo.
Thank you very much for share it with the community, this will help other users. We’ll put in contact with the Quick Start Guide’s author in GitHub to suggest this typo.
