## Ubuntu 16.04 (Xenial Xerus)
<a name="configure-ubuntu1604-for-hibernation"></a>

To configure Ubuntu 16.04 LTS to support hibernation, you need to install the linux-aws-hwe kernel package version 4.15.0-1058-aws or later and the ec2-hibinit-agent.

**Important**  
The `linux-aws-hwe` kernel package is supported by Canonical. The standard support for Ubuntu 16.04 LTS ended in April 2021, and the package no longer receives regular updates. However, it will receive additional security updates until the Extended Security Maintenance support ends in 2024. For more information, see [Amazon EC2 Hibernation for Ubuntu 16.04 LTS now available](https://ubuntu.com/blog/amazon-ec2-hibernation-for-ubuntu-16-04-lts-now-available) on the Canonical Ubuntu Blog.  
We recommend that you upgrade to the Ubuntu 20.04 LTS (Focal Fossa) AMI or the Ubuntu 18.04 LTS (Bionic Beaver) AMI.

1. Update the kernel to `4.15.0-1058-aws` or later.

   ```
   [ec2-user ~]$ sudo apt update
   [ec2-user ~]$ sudo apt install linux-aws-hwe
   ```
