The problem seems to be caused by having two shims, as we get the "Bootloader has not verified loaded image" messages when loading this way, but if we instead chainload the local grub directly, things work.
So it seems like local shim does not correctly uninstall and replace remote shim protocol or something like that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1865515 Title: Chainbooting from grub over the network to local shim breaks chain of trust To manage notifications about this bug go to: https://bugs.launchpad.net/maas/+bug/1865515/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
