Error: Cannot retrieve metalink for repository: fedora.

I have upgraded to F11 using preupgrade. Everything went fine.
Now I am trying to update with yum but I get these errors.

# yum update
Plugin "filter-data" can't be imported
Loaded plugins: aliases, allowdowngrade, dellsysidplugin2, downloadonly, fastestmirror, kernel-module, keys, list-data, presto, refresh-packagekit, versionlock
Loading mirror speeds from cached hostfile
Error: Cannot retrieve metalink for repository: fedora. Please verify its path and try again

If i disable fedora, I get this:

# yum --disablerepo=fedora update
Plugin "filter-data" can't be imported
Loaded plugins: aliases, allowdowngrade, dellsysidplugin2, downloadonly, fastestmirror, kernel-module, keys, list-data, presto, refresh-packagekit, versionlock

Could not retrieve mirrorlist http://mirrors.rpmfusion.org/mirrorlist?repo=free-fedora-11&arch=i386 error was
[Errno 4] IOError: <urlopen error [Errno -2] Name or service not known>

Cannot find a valid baseurl for repo: rpmfusion-free

How can I fix this?

I think there is something wrong with metalink generation. Try comment out the metalink url and uncomment the mirrorlist url things should work.

I suggest disabling all those plugins too, at least temporarily. For example, I only use fastestmirror, presto, and refresh-packagekit.

I am using the mirroslist which is a metalink.

[fedora]
name=Fedora $releasever - $basearch
failovermethod=priority
#baseurl=http://download.fedoraproject.org/pub/fedora/linux/releases/$releasever/Everything/$basearch/os/
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=$basearch
enabled=1
metadata_expire=7d
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch

If i comment out the mirrorlist and use the baseurl in every repo file, i get this:

# yum update
Plugin "filter-data" can't be imported
Loaded plugins: aliases, allowdowngrade, dellsysidplugin2, downloadonly, fastestmirror, kernel-module, keys, list-data, presto, refresh-packagekit, versionlock
