With the removal of the old delivery-cli packages we inadvertently caused an issue with delivery-cluster and build nodes. The delivery_build cookbook, which is used by delivery-cluster and build nodes, was still pointing at the old delivery-cli packages and would error out when it was run. This cookbook has been updated to now point to the delivery-cli bundled in Chef DK. If you ran delivery-cluster or did a CCR on a build node and encountered an error, please run it again. It will pull in the latest delivery_build cookbook and the issue will be fixed. No other action is needed on your part.
If for some reason you are using the delivery_build cookbook in a different context or have it pinned, you will need to update it to version 0.4.28 to address this issue.
