@peterbarker. Thanks for the quick response Peter. I'm new to Ubuntu and command line instruction but have tried xz util and several others mentioned on the Linux forums. I was able to unzip the Edison tar and flash without problems on both systems, both with command line and commercial programs. I'm a little confused as to what to do with the script in your response. I did install dpkg-dev and tried that with no results. The best I have been able to come up with is an empty folder labeled apsync-tx1-latest.img. It's the old story, I know enough about this to get myself in trouble. I'm going to slog through this some more after work.
