software update & SELinux libraries

[Lowell]

Hi!
Three times  over the last few days, the Software Update program has 
announced that it has 10 updates it wants to install. I okay this, 
provide the password to approve it, the program gets the list of pkgs. 
(a few SELinux libraries, a microcode reader, an ffmpeg lib, among 
others) downloads, attempts to install, fails and closes; the details 
say "Fail;fail'
This is Fedora 17 64-bit Gnome on a Toshiba Satellite A665.
    Thought you might like to know of this.
thx
