8.2-759 Running 'Software update' to upgrade from Measure 17 to Measure 19 restarts sugar.

Running "Software update" indicates that there is an update from  
Measure 17 to Measure 19.
When I click "Install selected" Sugar restarts.
Then when I try Software update again and attempt to install Measure  
19 it just refreshes but never successfully does the install.
I can loop over and over clicking "Install selected" in this secenario.
