Thanks for the reply, it helped a lot -- I seem to have one problem remaining (below).

I did some drastic deletions in /var, and then tried upgrade again and it became apparent that I had deleted some essential directories and files, but the error messages told me what they were so I recreated them. Aside: I should increase the size of /var and maybe /boot -- they both (of similar size) seem very adequate in my Wheezy system (still in service). And then, ran apt-get upgrade again and the problems and that got rid of the problems with: linux-image-3.16.0-7-amd64 linux-image-amd64 initramfs-tools (I feel much better now that the linux images are installed.) But now I'm at this point: root@s31:~# apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade... Done The following packages have been kept back: firmware-linux-nonfree 0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded. root@s31:~# I don't know that I'm worried about that, but if someone knows what I need to do, I'll try it.
