It looks like your code pasted incorrectly. > It pops up the gksudo dialog, and then fails. But i don't get any stdout or > stderror. Fails how? Is there an error? Does it hang? Does nothing happen at all? My initial thought is that you might want to try using Popen.communicate instead of stdout.read in case you're getting deadlocked. See the big red warning below https://docs.python.org/3/library/subprocess.html#subprocess.Popen.stdout -- https://mail.python.org/mailman/listinfo/python-list
