LinuxQuestions.org - dpkg error when trying to reinstall kernal from a live session using chroot

I have messed up using a boot-repair CD and have ended up either removing or partially removing (not sure which tbh) my kernal.

I have booted up an Ubuntu-Gnome 16.04 live session (this is the same distro/release as the damaged system, not sure if it helps at all but though it sensible) chrooted into the damaged system using instructions found here:-
http://askubuntu.com/questions/28099.../166010#166010

I have got as far as the command to install the new kernel and am getting:-

root@ubuntu-gnome:/# apt-get install linux-image-generic

Can someone with more brains than me tell me how I get out of this mess! I have tried removing 'linux-image-extra-4.4.0-28-generic' both with apt and directly with dpkg to no avail and now run entirely out of ideas!!
