I've got Ubuntu 14.04 Desktop ed. w/ kernel ver. 3.16 About a month ago I allowed the system to upgrade the kernel to ver. 4.xx, but after that I couldn't boot my system, so I re-installed everything from Clonezilla image and now I have again 3.16 It's all nice, but everyday I see this annoying upgrade proposal and what's even worse is that I think that I can't install any Ubuntu updates, since I get this kernel upgrade box and when I close it, then there's no update at all. You can take a look at those two print screens I've added.
