ubuntu8.04下安装sybyl出现了问题，恳求高手帮我，万分感激！！

[蓝色风云]

我在ubuntu 8.04下装sybyl7.3的时候，yum,python-sqlitecachec,libmotif3几个软件都装好了，在用cd安装时，执行install.sh 安装文件都一切正常，浏览器选择的时候也是选的firefox,但是在最后一步点install后，安装程序就卡住了，上面显示安装进度一直都是0，而且也无法退出安装，只用重启计算机。用DVD装的时候，安装命令一输入过去，终端就显示Permission denied我装了几次都是这个情况，我是菜鸟，请高手指点！ 万分感激！！！！！！！

补充一下：
下面是出错的代码：
[: 14: /usr/tmp/TA_INSTALL6586: unexpected operator

Exception in Tkinter callback
Traceback (most recent call last):

是不是因为python版本过高引起的，如果是的话怎么装python2.1版本？ 请高手赐教
