[问题]软件安装的时候总提示权限问题

[overloads]

网上下载了opera ，解压以后里面有个install.sh文件，按照网上的说明在终端中执行 sh install.sh后出现以下问题，软件安装不成功。请问高手这是怎么回事情阿？
提示如下：
lzt@lzt-laptop:~/桌面/opera$ sh install.sh

Files will be installed as follows:
-----------------------------------------------------------
Wrapper Script : /home/lzt/bin
Binaries : /home/lzt/lib/opera/9.23-20070809.5
Plugins : /home/lzt/lib/opera/plugins
Shared files : /home/lzt/share/opera
Documentation : /home/lzt/share/doc/opera
Manual page : /home/lzt/share/man
-----------------------------------------------------------
Is this correct [ y,n,c | yes,no,cancel ] ?
y

这个？？

用你的linux下浏览器登陆opera官方网站，然后 下载

直接就是和你的系统对应的deb格式的安装包

[kg7726]

在前面加上sudo 试试

[kg7726]

/etc/opera6rc
/etc/opera6rc.fixed 要根用户才能读写的

sudo sh install.sh
