17.10 - Can't Remove Old Kernels Due to Unmet Dependencies

I'm trying to remove old kernels on Ubuntu 17.10, but am being hit with an unmet dependencies error. My current kernel is linux 4.13.0-38-generic.

My output from dpkg -l | grep linux-image | awk '{print$2} is this:

linux-image-4.13.0-36-generic

linux-image-4.13.0-37-generic

linux-image-4.13.0-38-generic

linux-image-4.13.0-39-generic

linux-image-extra-4.13.0-36-generic

linux-image-extra-4.13.0-37-generic

linux-image-extra-4.13.0-38-generic

linux-image-extra-4.13.0-39-generic

linux-image-extra-4.13.0-41-generic

linux-image-generic

When I try to remove older kernels (sudo apt-get purge linux-image-x.x.x-x-generic), this is the error:

Reading package lists... Done

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:

linux-image-extra-4.13.0-41-generic : Depends: linux-image-4.13.0-41-generic but it is not installed
linux-image-generic : Depends: linux-image-4.13.0-41-generic but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

To fix the broken dependencies, I use sudo apt --fix-broken install, click Yes when asked whether I want to continue, and get this output:
