july 8(?) update fail nautilus dropbox

[dale kain]

26 updates.  24 went thru it looks like after unchecking dropbox, but 2
did not go through as could not get mirror for upgrade to nautilus
dropbox.  Tried may times and finally today, unchecked the box for
dropbox and went ahead with the rest of the updates ( includes fedora
core update)  
Now will not boot to new core.  Had to go back to previous core.  What
is still left to update is one nvidia and nautilus-dropbox.

Do I just wait for the dropbox update?  It keeps informing me there are
no more mirrors to try
