 If the image build fails with an error such as "/Error reading from server. Remote end closed connection/" then you can specify a debian package mirror repository manually with:
 
     Cubietruck (Cubieboard 3)

 If there is no existing image available then you can build one from scratch. See the section above on how to do that. If an existing image is available then you can download it and check the signature with:
 

src/freedombone-image-makefile

 	$(SIGN)
 	@echo "Build complete."
