Hi friends I told you about after update yum is not working I have got solution.

resolved  token no 210

I installed yum forcefully by using command

rpm -ivh --force yum

after I updated yum yumex

then all updates from fedora are working but updates by rpmfusion are not working.

so for this also the above solutions applies find updates using yumex it will download the packages to 

/var/cache/yum

to sub directory rpmfusion-<free/nonfree><-updates>/packages then use
rpm -ivh --force <package>

if dependencies exists install updates first.
