This is exactly the problem. UUIDs must be unique. And it doesn't seem
to be GRUB misdetection since there is no by-uuid entry pointing to
sdg1. The cause of UUID collision is usually if one copies partition
without regenerating UUID. Another possible reason is a buggy formatting
tool. You need to fix the UUID collision and then rerun update-grub.
