I also face this issue with nodes running on Hyper-V 2016 and enabled Secure Boot (Microsoft UEFI cert.).
My node (with deployed Ubuntu 17.10) shows following warning: --- Bootloader has not verified loaded image. System is compromised. halting. --- After a few seconds, the node powers off. I'm currently using MAAS version: 2.3.0 (6434-gd354690-0ubuntu1~17.10.1) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1711203 Title: Deployments fail when Secure Boot enabled To manage notifications about this bug go to: https://bugs.launchpad.net/curtin/+bug/1711203/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
