Thats the Fedora 14 key. ;)

I think we should change that probibly to avoid --skip-broken there. 
Instead you should not use --skip-broken and should look at removing
packages that can't be updated. (ie, orphans in the new release).

You need to import the Fedora 13 key above, instead of the 14 one. 
The fedora-release you have installed doesn't match the new keys, so
you need to import those first.
