Hi all,

[Errno 4] IOError: <urlopen error <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

I am using centos 5.5 64 bit version

How to fix this error ?

the error ? at this time i do not know
BUT "yum install gcc" is the WRONG command

Code:

yum grouplist
-- then from that list --

yum groupinstall " Development Tools" Development Librarys " 

-- and the optional " Gnome Development "

but as to the error ?
what did you do last ? Before this started , what did you install ?

thanks for that information, BTW , my IO error disappeared when I changed my address of my proxy server.

the fact you were using a proxy in the FIRST place would have been very nice to know about in the first post
