I have searched online and I have followed suggestions in Terminal, none of have worked for me. Below is issue I am having. Seems as though code to purge old kernels is broken, but to fix it I need to have more space, which is my entire purpose to begin with. I am very much new to Linux and am by no means a coder, so please be plain with me.

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
    linux-image-extra-4.13.0-36-generic : Depends: linux-image-4.13.0-36-generic but it is not installed
    linux-image-generic-hwe-16.04 : Depends: linux-image-4.13.0-36-generic but it is not installed
    linux-signed-image-4.13.0-36-generic : Depends: linux-image-4.13.0-36-generic (= 4.13.0-36.40~16.04.1) but it is not installed
E: Unmet dependencies. Try using -f.

Since you have run out of space, apt won't run; and thus, any automated fix will also fail. You need to manually free up some space in the /boot/ directory. One way to do this is delete the system maps for the kernels you are going to remove. If this doesn't give enough room, delete the initrd for some of the kernels. Note: you will need root privelage to remove files in /boot/.

  • any links you can provide on how to do that? Like I said I am using this cause its free and legally so. I am still not up to par on ins and outs of fixing this stuff. Trying to learn though. – Hunter Mar 19 '18 at 21:43
