Hi, I upgraded my server from 12.04 to 14.04 and I want to use the new kernel but I don’t see it available in the Settings > Kernel > dropdown list. This is the kernel I want to use:

root@dev:~$ ls /lib/modules
total 8.0K
drwxr-xr-x 5 root 4.0K Nov  7 17:07 3.13.0-100-generic/
drwxr-xr-x 4 root 4.0K Nov  7 17:09 3.8.0-29-generic/

but 3.13.0-100-generic is not available. It seems 3.13.0-91-generic is the highest.

You need to update to internally managed kernel. Go to Control Panel, select your Droplet, click Kernel. From drop down select GrubLoader v0.2 and change kernel to it. When it does finish power off your Droplet and power on again (power off is required, restart will not change to new kernel).

With this, you can manage kernels from Droplet. If you execute:

  • sudo apt-get update && sudo apt-get dist-upgrade

This command will update your Kernel to latest available - 4.8.x.
For specific kernel you’ll need to specify which one you want.

All I wrote above is available in How To Update Kernel. Especially pay attention to changing to GrubLoader and to Installing an Arbitrary Kernel on a Droplet if you want specific version.

Updating the kernel on your DigitalOcean Droplet is a straight forward process that differs slightly based on the Droplet's operating system. In this guide, we'll walk you through the process of updating your kernels for DigitalOcean Droplets.
