As far as I can tell, the command is correct, ASSUMING your input file is a valid gzipped tar file. Your output says that it isn't. If you downloaded the file from the internet, you probably didn't get the entire file, try again.

Without more knowledge of the source of your file, nobody here is going to be able to give you a concrete solution, just educated guesses.
