If you want to upgrade your Droplet to the latest kernel version, there are two ways to do it: The first section ( 3.13.0-43-generic in this example) is your Droplet’s current kernel version and the second is its architecture ( x86_64 in this example, i.e., 64-bit). The output looks similar to 3.13.0-43-generic x86_64. Once your Droplet is using internal kernel management, you can upgrade its kernel.īefore upgrading your kernel, you can use the command uname -ir to get the version of the kernel that your Droplet is currently using and your system’s architecture (32-bit or 64-bit).

If your Droplet is using legacy kernel management, you can switch to the DigitalOcean GrubLoader kernel to support internal kernels. To revert, simply select ‘Original Kernel’ and follow the same process. Then power off the server from the command line and boot it from the control panel and the new kernel will be active. If you see a Select a Kernel menu with a Change button and the following description instead, your Droplet is using legacy external kernel management: Instead, you can upgrade the kernel from within the Droplet. The kernel for this Droplet is not managed within the control panel. If the kernel management page has the following message, your Droplet is set to use internal kernels natively: If you’re not sure whether your Droplet manages its kernels internally, visit its detail page in the control panel and click Kernel in the navigation. Verify the Droplet’s Kernel Management Methodīefore you can upgrade your Droplet’s kernel, you need to veirfy that your Droplet is using internal kernel management.Īll Droplets created after March 2017 use internal kernels by default, and older Droplets can be configured to support internal kernels with the DigitalOcean GrubLoader kernel. Power off the Droplet, then power it back on.

Upgrade the kernel using a package manager. Verify that the Droplet uses internal kernel management. To upgrade a Droplet’s kernel to the latest supported version, you need to do three things: Each Droplet you create is a new server you can use, either standalone or as part of a larger, cloud-based infrastructure. DigitalOcean Droplets are Linux-based virtual machines (VMs) that run on top of virtualized hardware.
