Maybe it is a typo? Should not be there "diffstat" instead? https://www.imx6rex.com/open-rex/sof...ine-for-yocto/

Please, use the same version of Ubuntu which is used in the course. Do not use different version of ubuntu - you will have problems. I can see, that you are using Ubuntu 18, it is recommended to use Ubuntu 14 - check out beginning of the course.
