关于显卡驱动的安装问题

我的显卡是ati radeon 9200，但驱动老装不上。我先从官网上下了ati-driver-installer-8.28.8.run，然后按照官网的安装方法输入sh ./ati-driver-installer-8.28.8.run，结果：
jiajia@jiajia-desktop:~$ sudo sh ./ati-driver-installer-8.28.8.run
Creating directory fglrx-install
Verifying archive integrity... All good.
Uncompressing ATI Proprietary Linux Driver-8.28.8.....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
-e ==================================================
-e ATI Technologies Linux Driver Installer/Packager
-e ==================================================
./ati-installer.sh: 165: Syntax error: Bad substitution
Removing temporary directory: fglrx-install

没有出现安装界面。为什么装不了？怎么解决？
