请教：spb for linux 在ubuntu下如何安装

在下最近正努力尝试在ubuntu9.04(debian)下安装spb
我有15.5版for linux 和15.7(在ourdev上下载的)版 for linux。但安装不成功，下面是具体问题

（1） 安装15.5的时候出现错误，具体情况如下：
 
（确认完安装信息后提示的错误）

（然后经如Updating package installation information，出现连串点号，之后是如下错误）

(之后就回到了mainmenu)

（2） 15.7的安装，就是需要installscape，但是不知道哪里有，cadence官方网站下好像不能下(需要注册，但是注册需要特殊的认证，好象是买了产品才有的)


希望在linux下安装了spb的前辈指教。^^最好能给个方便的联系方式，以便请教。
