  <p>When I try to remove using below command I am getting error 
  command  sudo apt-get remove linux-image-4.4.0-75-generic</p>
  
  <p>error:</p>

  You might want to run 'apt-get -f install' to correct these:
  The following packages have unmet dependencies:
   linux-image-extra-4.4.0-75-generic : Depends: linux-image-4.4.0-75-generic but it is not going to be installed
   linux-image-extra-4.4.0-89-generic : Depends: linux-image-4.4.0-89-generic but it is not going to be installed
   linux-image-generic-lts-xenial : Depends: linux-image-4.4.0-89-generic but it is not going to be installed
  **E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).**

  <p>even I run this apt-get -f install command I get this similar error for linux-image-4.4.0-89-generic</p>
  
  <p>In the dpkg --list 'linux-image*'  list I can see this linux-image-4.4.0-89-generic image uninstalled .. Remove Purge all these commands are not working, can anyone please give me any solution for this problem?</p>
