之前申请Kubuntu时不确定邮编，就取消了。过了半个月再申请就提示这个。Demand for Ubuntu CDs is very high, and we're trying to ensure that we have enough CDs for those who really need one. We've noticed that you've already received CDs of several previous Kubuntu releases. You can help us ensure the continued availability of Kubuntu CDs by
•upgrading to the new release without a CD
•downloading your own CD for free
•becoming an Ubuntu member by contributing to Kubuntu, and thereby becoming eligible for more CDs
Thanks for your support of Kubuntu!
