fedora 20 yum update error - fedora

Question

I need to update my system and I just did a sudo yum update, and got the following errors.
--> Finished Dependency Resolution

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
I tried installing libcdio with, sudo yum install libcdio because of the dependency error as seen above, but it appears to be already installed.

* rpmfusion-free-rawhide: ftp.nluug.nl
* rpmfusion-nonfree-rawhide: ftp.nluug.nl
* updates: ftp.nluug.nl
Package libcdio-0.90-3.fc20.x86_64 already installed and latest version
Nothing to do
Please also note that I have tried these two commands.
yum clean all and
yum clean metadata
Edit
when I try and install rpmfusion for fedora 20, it wouldn't let me, since it already has a the fedora 21 repo already installed.
sudo rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-20.noarch.rpm

Answer 1

The rpmfusion-free-rawhide is targeting fc21. Your system is fc20. As such the rpmfusion-free-rawhide RPMs are depending on versions of system packages newer than what your default repositories (and your installed system) have available.
You can either upgrade your system to fc21 or find an rpmfusion repository that targets fc20.
