高手解决一下
不知怎么搞的，这几天安他软件时，老出现

installing f-prot
Downloading file fp-linux-ws.tar.gz.md5 from ftp://ftp.f-prot.com/pub/linux/
目录“pub/linux/”不存在。

Download failed. Please make sure that
your computer is connected to the Internet.
If you see this error although you are
connected, either the server is down or the
download location has changed. In the latter
case you can still download the files manually.
