求VPS
DA授權后臺是沒有Unbuntu選項的，Ubuntu和Debian對應起來即可。
可以通過http://www.debian.org/releases/查看現在Debian發行版最新情況。
If my memory is correct, any Ubuntu version after (and including) 11.10 uses Debian 7, thus it’s not yet supported.Versions 9 and 10 (for the most part) use Debian 5, so things in betwen (prior to 11.10) would use Debian 6.If unsure, just install Debian 6. Check the /etc/debian_version prior to installation.
如果內存允許，11.10（包含）以后的Ubuntu，都可以和Debian7對應，但是目前不支持Debian7；Ubutu9和Ubuntu10，和Debian5對應，Ubuntu9(10)到Ubuntu11.10之間的Ubuntu和Debian6對應。
