Yum errors on rpmfusion in F10: Please help

[Dean S. Messing]

Recently did a fresh install of F10. All updates (a boatload of them!)
as of yesterday.  Disabled IPv6 (in modprobe.conf) Disabled ip6tables
(chkconfig) and rebooted.  The ipv6 module is not loaded.

Nonetheless, like some others on the list I am getting this error from
yum after installing the rpmfusion repos:

[root at neuron ~]# yum  update
Loaded plugins: refresh-packagekit
Could not retrieve mirrorlist http://mirrors.rpmfusion.org/mirrorlist?repo=nonfree-fedora-updates-released-10&arch=i386 error was
[Errno 4] IOError: <urlopen error (-2, 'Name or service not known')>
Error: Cannot retrieve repository metadata (repomd.xml) for repository: rpmfusion-nonfree-updates. Please verify its path and try again

These repos were installed using the command suggested by Kevin Kempter:

rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

which installed just fine.

In fact:

[root at neuron ~]# rpm -qa | fgrep rpmfus
rpmfusion-nonfree-release-8-6.noarch
rpmfusion-free-release-8-6.noarch

I can get to the metadata file "repomd.xml" just fine by plugging the
URL from the rpmfusion repo into Firefox, but try as I might, yum
refuses to go there or work at all unless I disable the rpmfusion
repos.

Can anyone help me (other some others) fix this?
Thanks

Dean
