We reverted nullboot to 0.5.0-0ubuntu3 with shim 15.7 prior to the release of Noble. We have identified and fixed the issue in encrypt-cloud-image but we are still waiting on Microsoft to deploy the new version of tool in their provisioning backend. Once this will be done we will be able to release a new version of nullboot with shim 15.8.
