Installing Free and Nonfree Repositories
We have two separate software repositories:
free for Open Source Software (as defined by the Fedora Licensing Guidelines) which the Fedora project cannot ship due to other reasons
nonfree for redistributable software that is not Open Source Software (as defined by the Fedora Licensing Guidelines); this includes software with publicly available source-code that has "no commercial use"-like restrictions
Installation can be done either using a web browser, or via the command line.
Graphical Setup via Firefox web browser
First enable access to the free repository. For users of gpk (gnome package kit) or kpackagekit in Fedora that is easy and basically only one step: just click on one of the following files, depending on what distribution you use and then follow the default options that Firefox and Package Kit offer by clicking Enter a few times (¹):
Once that succeeds, you can enable access to the nonfree repositories by clicking on one of the following files, depending on what distribution you use and then follow the default options that Firefox and Package Kit offer by clicking Enter a few times(¹):
(¹) Once you clicked on above link Firefox will ask you how to Open the file. Here you can simply use the default and open the file with the default application Package Installer. Then Firefox will call Package Kit, which asks Do you want to install this file ?. Click OK to begin install; Package Kit then will complain about a Missing security signature; once you tell Package Kit to install the package nevertheless it will move on and install it. That's all.
Command Line Setup using rpm
To enable access to both the free and the nonfree repository use the following command:
Fedora 22 and later:
sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
RHEL 6 or compatible like CentOS:
sudo yum localinstall --nogpgcheck https://download1.rpmfusion.org/free/el/rpmfusion-free-release-6.noarch.rpm https://download1.rpmfusion.org/nonfree/el/rpmfusion-nonfree-release-6.noarch.rpm
RHEL 7 or compatible like CentOS:
sudo yum localinstall --nogpgcheck https://download1.rpmfusion.org/free/el/rpmfusion-free-release-7.noarch.rpm https://download1.rpmfusion.org/nonfree/el/rpmfusion-nonfree-release-7.noarch.rpm
Note : If sudo is not properly set on your installation, you can replace 'sudo' with 'su -c' in the commands above.
