I am running Ubuntu Server 14.04 LTS on a desktop at my home that I was intending to turn into a server, but I never really did much on it. I then decided to turn it into a send-only SMPT server, but when I tried sudo apt-get install postfix to install postfix, I got this error:
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-image-extra-3.19.0-42-generic : Depends: linux-image-3.19.0-42-generic but it is not going to be installed
linux-image-extra-3.19.0-56-generic : Depends: linux-image-3.19.0-56-generic but it is not going to be installed
linux-image-generic-lts-vivid : Depends: linux-image-3.19.0-56-generic but it is not going to be installed
Recommends: thermald but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
I tried running sudo apt-get -f install, but that didn't work:

I tried installing other packages and the error persists across all uses of apt-get install.
I also followed the instructions at apt-get has unmet dependencies, but apt-get -f install doesn't solve problem to run sudo apt-get clean, but that still didn't solve my problem.
So what is wrong? What must I do to get apt-get working again?
I do not know much about this issue, so I may not have provided all the necessary information. Please comment if I need to add more.
