Thank you. Thank you! Thank you!!!! Once I figured out I had to put "sudo" in front of the commands (was working on this while Fabi was posting) and figured out how to get the, in my case, 2 files out of the cache directory and ran the update manager again and restarted -- Wooo Hoooo!!!!
Again, thanks to everyone!
(not nearly so technical as folks who "know" me think I am!)
