i fiddled around with Synaptic until i could get "Broken" to show up in the list of possibilities at the left of the window. Then it was just a matter of clicking on "Broken" and checking the right hand window to see which programs appear with a red box. Deselect the file(s) and the select Apply to download the rest of the programs.
i had to do this again yesterday - i guess it's still being "held back".
i hope this helps... Have a wonderful morning!
