Hi,
[root@deymos ~]#rpm -Uhv
ftp://download.fedora.redhat.com/pub....rc.noarch.rpm
edit yum.repos.d repositories and enable the new ones
[root@deymos ~]# cat /etc/yum.repos.d/fedora-rawhide.repo
# These packages are untested and still under development. This
# repository is used for development of new releases.
#
# This repository can see significant daily turnover and major
# functionality changes which cause unexpected problems with other
# development packages. Please use these packages if you want to work
# with the Fedora developers by testing these new development packages.
#
#
fedora-test-list@redhat.com is available as a discussion forum for
# testing and troubleshooting for development packages in conjunction
# with new test releases.
#
# More information is available at

# Reproducible and reportable issues should be filed at
