can anyone help me please
my problem is

# yum install bridge-utils iproute sysfsutils
Setting up Install Process
Setting up repositories
Cannot find a valid baseurl for repo: updates-released

I can't figure it out why why why
I tried many things, but it doesn't work

help me please.

show us the updates-release repo file.

which file do you want to view?
I am some kind of new, sorry

/etc/yum.repos.d/updates-released.repo

what have you already tried then? what didn't work?

[updates-released]
name=Fedora Core $releasever - $basearch - Released Updates
#baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/updates/$releasever/$basearch/
mirrorlist=http://fedora.redhat.com/download/mirrors/updates-released-fc$releasever
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora

edit
fedora-updates.repos, fedora-extras.repos, fedora.repos,
and i install new yum software, but it cause me a problem.

ok edit that file, remove the # from the baseurl line and add one to the mirrorlist line and try that... can you actually get on line at all though? i'd wonder if yum is actually at fault... can you see the web page at http://fedora.redhat.com/download/mi...s-released-fc5 cos that's the file that yum is trying to download.

I edit that file. following is what I edit it.
[updates-released]
name=Fedora Core $releasever - $basearch - Released Updates
baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/updates/$releasever/$basearch/
#mirrorlist=http://fedora.redhat.com/download/mirrors/updates-released-fc$releasever
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora

but it still dosen't work.
the new error message is

# yum -y update
Setting up Update Process
Setting up repositories
Cannot open/read repomd.xml file for repository: updates-released
failure: repodata/repomd.xml from updates-released: [Errno 256] No more mirrors to try.

ok, i vote for a network probelm then. as above you need to be able to reach that url.

I don't think so, cause last time i used to install FC5, and on FC5 "yum -y update" worked perfectly. I don't understand why on FC4 it doesn't work. Actually, I am trying to install Xen3.0 on FC4, to create domainU I have to use yum command to install FC4 on domainU. If yum command doesn't work I can't finish creating domain U.

ok, one more time... can you reach that URL?? forget yum totally. just use a web browser. yum is apparently not at fault in the slightest...

anyway thanks you guys. I'll talk to my teacher.
