/boot filled up with kernel updates, simple solution required

I ran the update manager as normal and it siad /boot had run out of space and gave a command to fix it which did nothing "sudo apt-cache clean" or similar.

I may have fubared my system trying to manually remove old kernel packages, but even that didnt free up enough space, then removing the kernel updates manually form the update manager etc.. but still,

This was a default eOS install and the boot partition can fill up, there needs to be a non-tech way to the user to move past this.

I'd suggest just removing the old kernels automaticly and moving them onto the new ones.

Yeah, there's not space in my /boot to compile the new kernels.
