I tested this locally by creating a MAAS preseed that adds my PPA. And it works.... sort of. The kernel no longer causes flash-kernel to be installed, but unfortunately flash-kernel is *pre-baked* in the arm* cloud images, so we'd have to remove it from them too.
RE: EFI-STUB - GRUB is the default way to boot Ubuntu on EFI systems. Users can choose to boot using EFI-STUB, but they can also remove any Recommended packages. Adding grub-efi-arm64 to Recommends will also get arm64 on-par with amd64, which also recommends GRUB. ** Also affects: cloud-images Importance: Undecided Status: New ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1918427 Title: curtin: install flash-kernel in arm64 UEFI unexpected To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1918427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
