Welcome to rpm.livna.org, a repository of add-on RPM packages for Fedora as well as RHEL (version 5 and later) and its compatible derivates like CentOS.
rpm.livna.org in the past provided many useful packages that those distributions rpm.livna.org supports did not want to ship for one reason or another. In 2008 rpm.livna.org merged with two other package repositories into RPM Fusion. All packages have been moved there except one that RPM Fusion for various reasons didn't want to take. Hence rpm.livna.org will remain running to ship just that package. rpm.livna.org is fully compatible with RPM Fusion and all other Fedora add-on repos that don't ship the package that rpm.livna.org ships.
Install the livna-release package by clicking on this link and hitting Enter a few times.(¹)
Install the livna-release package by running this command(²):
sudo rpm -ivh http://rpm.livna.org/livna-release.rpm
In Fedora 10 and later you can also use the rpm.livna.org repository directly during install. It works similarly to the scheme that RPM Fusion uses. As repo URL just use http://rpm.livna.org/repo/10/i386/ for Fedora 10, i386; adjust accordingly for other Fedora releases or other architectures like x86_64, ppc or ppc64. Please note that you must not check the "URL is a mirror list" checkbox for rpm.livna.org.
Livna is closely associated with RPM Fusion. Therefore, please use the RPM Fusion mailing lists for discussing and reporting bugs or submitting spec file improvements; E.g.
su -c "rpm -ivh http://ftp-stud.fht-esslingen.de/pub/Mirrors/rpm.livna.org/livna-release.rpm"
for example.
