Ubuntu xenial upgrade#
The upgrade process in that case becomes a change management process involving risk analysis, stakeholder communication and possibly the upgrade of existing solutions, in addition to the actual operating system upgrade.
Ubuntu xenial software#
Such complex scenarios result in a dependency on software stacks (e.g., Java, python) that have certain properties in the upgraded system that either got deprecated, replaced or slightly changed behavior in the newer system. Typically enterprise solutions combine software from a variety of teams within an organization, in most cases there is an extended supply chain, involving software from 3rd party vendors, who in turn may have their own software vendors.
There are multiple deployment strategies and infrastructure options ( Canonical Openstack, Charmed Kubernetes or bare-metal), and depending on their usage and the policies in place can reduce specific risks such as downtime during upgrade, but there are certain common challenges. Transitioning to the latest operating system, although important due to performance, hardware enablement as well as new technology enablement benefits, is a complex process for existing deployments. If you are not a UA Infrastructure customer and need access to ESM, please get in touch with our team to learn more and enable ESM for your Ubuntu 16.04 systems.
Ubuntu xenial pro#
No actions are necessary with Ubuntu Pro to enable ESM. If you are an Ubuntu Advantage customer and need access to the ESM repository, credentials can be found by clicking on the ESM block of your subscription in the Ubuntu Advantage portal. You can access ESM with Ubuntu Pro on public cloud platforms, as well as with Ubuntu Advantage. Do not hesitate to get in touch with our team to discuss any additional questions on ESM for Ubuntu 16.04. This access permits organizations with workloads running on Ubuntu LTS releases to maintain compliance standards by providing a secure environment before upgrading can occur.įor users who need access to ESM, or have questions about this service, please refer to the questions below. Once the public Standard Security Maintenance window comes to a close, Ubuntu LTS releases have an additional five years of support (depending upon the release) through ESM, in addition to providing a built-in upgrade in-place path to the next LTS release.Īccess to ESM extends the LTS release coverage, allowing for continued security fixes for high and critical common vulnerabilities and exposures (CVEs) for the packages in the Ubuntu ‘main’ and ‘restricted’ archives for x86-64 architectures. Ubuntu long term support (LTS) releases provide a stable, enterprise platform for development and production, with five years of guaranteed public maintenance available. Ubuntu 16.04 is a Common Criteria certified operating system, providing access to FIPS 140-2 certified cryptographic modules with a solid history of timely security fixes. ESM is also available to personal users on up to three machines and Ubuntu members on 50 machines.
Xenial Xerus is still supported until April 2026 with Extended Security Maintenance (ESM) through Ubuntu Advantage for Infrastructure, and on the public cloud with Ubuntu Pro for AWS, Azure and Google Cloud. Ubuntu 16.04 LTS ‘Xenial Xerus’ transitions into the extended security maintenance (ESM) support phase at the end of April 2021 from its standard, five-year maintenance window for Ubuntu long term support (LTS) releases. This article was updated in September 2021 to reflect the new lifecycle of 16.04.
