I do the same and can resolve it but unbound sometimes forgets its
brain, which is fixed by restarting it. If that doesn't work, you will
want to shut down anything that could do a DNS resolution request, set
verbosity to 3 or higher in your unbound configuration and then
resolve cdimage.debian.org in order to debug the issue. You'll also
want wireshark listening on all interfaces and not resolving MACs/IPs
to names to help with the debugging.
