At the time of writing, RPM Fusion still has not published a link to the stable repo for Fedora 15. You may have installed the stable RPMs and got an error like this:
[Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-nonfree-fedora-15-arch
The workaround for now is to disable the GPG check.
Install as usual:
su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm'
, you should disable the gpgcheck option.
e.g. In your
gpgcheck=0 [rpmfusion-nonfree] name=RPM Fusion for Fedora $releasever - Nonfree #baseurl=http://download1.rpmfusion.org/nonfree/fedora/releases/$releasever/Everything/$basearch/os/ mirrorlist=http://mirrors.rpmfusion.org/mirrorlist?repo=nonfree-fedora-$releasever&arch;=$basearch enabled=0 metadata_expire=7d gpgcheck=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-nonfree-fedora-$releasever-$basearch
Or, you could download the gpg keys as stated in this post: NoteIts in Spanish.
