Como baixar o kernel dbgsym para 15.10?

Question

Eu tenho um problema ao tentar encontrar o kernel dbgsym dos repositórios ww. Infelizmente não consigo encontrá-lo. Meu sistema trava ao executar vinho e cromo e eu estou tentando ler o despejo de memória.

uname -r
4.2.0-25-generic

sudo apt-get install linux-image-$(uname -r)-dbgsym

E: Unable to locate package linux-image-4.2.0-25-generic-dbgsym
E: Couldn't find any package by regex 'linux-image-4.2.0-25-generic-     dbgsym'

sudo apt-cache search generic-dbgsym | grep kernel

cat /etc/apt/sources.list.d/ddebs.list

deb http://ddebs.ubuntu.com/ wily-security main restricted universe  multiverse
deb http://ddebs.ubuntu.com/ wily-updates main restricted universe multiverse
deb http://ddebs.ubuntu.com/ wily-proposed main restricted universe multiverse

Também tentei limpar as listas de repo apenas no caso de algo funky está acontecendo lá, mas eu ainda pareço ter os erros abaixo. Eu os limpei usando sudo software-properties-gtk
