The LXD build provider loads Ubuntu Minimal Cloud images. These images are available for x86 platforms only. Subsequently attempts to run ``snapcraft build --use-lxd`` on a non-x86 platform (arm64, s390x or ppc64el) result in this sequence of error messages: Launching a container. An error occurred with the instance when trying to launch with 'LXD': The requested image couldn't be found. Ensure that 'LXD' is setup correctly and try again. Changing snapcraft to load full cloud images or just using the standard LXD Ubuntu image server would most likely solve this issue. https://github.com/snapcore/snapcraft/blob/d59622a8100c021e02fb5a99947e42602d306ae2/snapcraft/internal/build_providers/_lxd/_images.py#L33
