E: 有一些索引文件不能下载，它们可能被忽略了，也可能转而使用了旧的索引文件。

9.10已经停止服务，所以没有源了。看下面帖子，改一下源，试试。

或者重装新版本吧。

那如果我从
http://dist.schmorp.de/rxvt-unicode/
下载的话，如何安装啊？

执行解压开的 ./install-sh ,提示找不到文件。

install-sh 的权限为: -rwx------

命令：sudo ./install-sh

./install-sh: no input file specified.



是不是不是这么安装软件的 ？

升级到ubuntu 11.10 了事 。
