Ubuntu 8.04 已经发布有一些日子了， Ubuntu 8.10 的第一个 Alpha 版 Ubuntu 8.10 Alpha 1 也即将发布。 想尝鲜的“小白鼠”可能已经按奈不住了吧！其实在 Ubuntu 8.04 发布后一周左右人的时间就人在社区里把 Ubuntu 8.10 的软件源帖出来，你只需添加并启用 Ubuntu 8.10 的软件源并可以升级到 Ubuntu 8.10 了。添加下面的 Ubuntu 8.10 软件源：

如果你不清楚怎么添加并更新 Ubuntu 8.10 的软件源，你可以参考《Ubuntu 软件源设置指南》 ，方法是类似的。在你更新完 Ubuntu 8.10 软件源的时候，你就可以把系统升级到 Ubuntu 8.10 了，操作方法和以前跨版本的升级方法相似。如果不清楚跨版本升级请 点击这里 。
升级完成后，打开系统监视器你会发现版本已经变为 8.10 ( intrepid )
PS：升级有风险，不建议大家这么做，但如果你愿意当“小白鼠”来体验或测试一下 Ubuntu 8.10 ，就 Do It 吧！
