cannot yum update
 

Good day to all linux experts

Could anyone help me I'm trying to update my linux CentOS 4 for my squid proxy server setup but I can't update it through 'yum -y update'. I tried yum clean all then yum -y update then again yum update all but still no luck I got this error messages...

The following web page has a typical centos 4 yum repository list for yum.conf

http://fortmunir.wordpress.com/2007/...entos-yumconf/

Perhaps you could use these and any special repositories you enabled to run yum.

Thanks for the reply ehawk could you please be specific of what I am going to do that file.
What I did is I rename the yum.conf to yum_orig.conf for backup purposes and then I make another file named yum.conf and the content is what you refer me at this site http://fortmunir.wordpress.com/2007/...entos-yumconf/, I even edited the file and uncommented the baseurl part

[base]
name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4
protect=1

#released updates
[update]
name=CentOS-$releasever - Updates
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos4
protect=1

but still no luck, now I got this new error messages

Are you trying to connect through a proxy? If so, can you circumvent it somehow?
