In accordance with the information shared in our latest blog post, it is important to note that Ubuntu 18.04 LTS, codenamed ‘Bionic Beaver,’ is approaching the end of its standard five-year maintenance period on 31 May 2023. Consequently, unless you hold an Ubuntu Pro subscription, updates for Ubuntu 18.04 LTS servers will cease to be available.

By subscribing to Ubuntu Pro, you can ensure that your Ubuntu 18.04 LTS deployment remains fully supported until 2028. This extended support period provides you with continued assistance and maintenance for your workloads running on Google Compute Engine (GCE).

To gain a comprehensive understanding of the implications and actions required if you currently have GCE workloads on Ubuntu 18.04 LTS, we invite you to refer to this blog for detailed information.

Upgrade to newer versions of Ubuntu

If you are contemplating upgrading your Ubuntu installation to a more recent version, there are a couple of options available. One option is to upgrade to Ubuntu 20.04 LTS directly. Alternatively, you can perform a fresh installation of Ubuntu 20.04 or 22.04 LTS and then adjust your applications accordingly.

For a detailed guide on how to upgrade your Ubuntu Server, please refer to the Ubuntu Server upgrade guide, which provides comprehensive information and step-by-step instructions.

Upgrade to Ubuntu Pro

If you require additional time to plan your upgrade or prefer to extend the lifespan of a project that doesn’t require immediate upgrading, Ubuntu Pro offers a suitable solution.

Ubuntu Pro is a subscription service provided by Canonical, offering enhanced security and compliance features while maintaining the familiar Ubuntu experience. With Ubuntu Pro, you gain access to “esm-infra”, which extends the coverage of LTS releases from the standard 5 years to 10 years from the release date. This extended coverage ensures that critical security vulnerabilities, identified as high and critical common vulnerabilities and exposures (CVEs), continue to receive security fixes for both x86-64 and arm64 architectures.

Additionally, Ubuntu Pro includes access to “esm-apps”, which provides security patching for over 23,000 third-party open-source applications available in the Ubuntu Universe repository.

By leveraging Ubuntu Pro, organizations with workloads running on Ubuntu LTS releases can uphold compliance standards by maintaining a secure environment without immediate upgrades.
