It turned out that I though that I was subscribed to "debian-kernel@l.d.o", but I wasn't. This is solved now. > What does file(1) say about them?

This is hard to answer properly. The image has "grub2" (the last 2.02~beta2-22+deb8u1 available on Jessie) installed and I can boot it on a local Xen installation as well on Oracle Cloud (using the custom kernel compressed with gzip). What I tried is the same process (extract-linux, generate initrd, update-grub) both on VirtualBox and Xen on Oracle Cloud. In VirtualBox, I got the error pasted on my first message. In Oracle Cloud I have no access to the boot logs to confirm if it happens to be exactly the same. -- Tiago "Myhro" Ilieve Blog: https://blog.myhro.info/ GitHub: https://github.com/myhro LinkedIn: https://br.linkedin.com/in/myhro Montes Claros - MG, Brasil
