New Ubuntu 16.04 Kernel not in the dropdown list

Hi,

I just upgraded from Ubuntu 14.04 to 16.04 (used this article as help https://www.digitalocean.com/community/tutorials/how-to-upgrade-ubuntu-12-04-lts-to-ubuntu-14-04-lts) and was about to upgrade my kernel to the new one downloaded during the process. My current Kernel is 3.13.0-57-generic and I want to switch to the one downloaded which is 4.4.0-71-generic. I see the kernel in my terminal when typing ls /lib/modules, however, it is not showing up in the Droplet Kernel dropdown list in the DO control panel.

btw. it’s really annoying to be forced to post at least one tag when asking a question, when there is nothing like “kernel” “ubuntu” or “upgrade”, pls change that to the behaviour of stackoverflow.

Thanks!
