John, I got a similar message. I googled the text of the message and found a recommendation for a solution. It involved listing up-gradable stuff, then upgrading the grub. My brain being as porous as it is, this is as specific as I can be. It was related to grub and grub-2, not grub-pc, but maybe trying the same with google would provide a similar solution. My impression is that there is something wrong with the package upgrading. -Denis
