由于ubuntu6.10 edgy不支持我的intel DG695主板，我只好拿β版的7.04 feisty来试试运气了。还好，一切顺利了，下面开始安装ZCS（zimbra collaboration suite）4.5.4！

由于ZCS尚未官方支持feisty，一帆风顺的安装似乎不可能了。不过feisty比edgy在底层结果上变动不大，只要安装了必要的软件包，让ZCS以为自己身在edgy即可。以下是我在zimbra论坛上得到的回复。Thanks, dijichi2 !

＃vim /etc/lsb-release
修改
DISTRIB_RELEASE=7.04
为
DISTRIB_RELEASE=6

这样ZCS就会认为自己在edgy上安装了。成功！
