My Ubuntu 14.04 droplet is still running 3.13.0-91-generic although there have been multiple patches since then, including security updates (Changelog). Nothing newer than "Ubuntu 14.04 x64 vmlinuz-3.13.0-91-generic" is available in the kernel drop-down menu. This is in the AMS3 region, if that matters.

That depends on when you created Droplet. In past, Kernels was managed from Control Panel. This was changed some time ago and now it can be updated via Droplet console (terminal/SSH). The only thing is what you need to do is to change from your current Kernel to Internally managed kernel.
After that you should be able to upgrade kernel from Droplet (e.g. apt-get upgrade && apt-get dist-upgrade).

To do it, follow DigitalOcean tutorial on How To Update Kernel

If this is the case, when you update you should see image like this

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.
  • I now see "DigitalOcean GrubLoader v0.2 (20160714) Ubuntu" in the control panel (so I guess I could go back to an externally managed kernel) but the droplet is running the latest version. Thanks!
