@juliank: The shim build is the same in both cases. The only difference is that one is signed by MS, the other self-signed. I did notice that key enrollment didn't work in my guest, which maybe a failure to execute mma64.efi, and therefore maybe related to bug 1864223.
My hypothesis is that the SB support for arm64 is not upstream, and there was a regression introduced when rebasing those patches on GRUB 2.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1862279 Title: arm64 Secure Boot fails w/ "error: cannot load image."
