The rawhide/COMPOSE_ID file on dl.fedoraproject.org is sometimes out of sync with the contents of the images directory. For example, currently COMPOSE_ID says Fedora-Rawhide-20260929.n.0, while the only image available is Fedora-Cloud-Base-Generic-Rawhide-20261002.n.0, so starting an instance from experimental/fedora-rawhide fails with: failed to download `https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Cloud/x86_64/images/Fedora-Cloud-Base-Generic-Rawhide-20260929.n.0.x86_64.qcow2`: unexpected HTTP status Not Found Instead, get the image file name from the CHECKSUM file in the images directory, which describes the images actually present there. As a bonus, this also gives us the image digest. While at it, add --retry to curl invocations. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
