This will be enforced starting May 1, 2021.
This is a notice regarding releases of Ubuntu that will be reaching, or have reached, the end of their standard support period. These releases are no longer on topic effective the above enforcement date.
The following version of Ubuntu and its derivatives officially reach End of Standard Support on April 30, 2021:
- Xenial Xerus (16.04)
New questions specific to the above versions of Ubuntu posted on or after the enforcement date may need to be considered offtopic. Old questions (before the end of standard support date) that are still being answered regarding these releases should have a comment included on them about upgrading to a supported release to get continued support for their versions of Ubuntu.
This information can be confirmed via the 16.04 announcement message regarding when 16.04 enters ESM. (this was sent out on March 12, 2021 as is typical ahead of a release leaving standard support).
Per discussions related to scope and on-topic posts effective April 12, 2021, End of Standard Support and End of Life are treated the same way with posts becoming 'Offtopic' at that point.
There is an Extended Security Maintenance program as part of the Ubuntu Advantage system. This does NOT give ongoing support for bugs and issues with 16.04 and is only designed to provide ongoing security updates for legacy systems you cannot yet migrate to newer software versions. This is a Canonical commercial service, and though there is a 'free' version of ESM it does not make a release 'on topic' here on Ask Ubuntu.
If you have a concern with this policy, raise it as a separate Meta issue. DO NOT post to this thread regarding your concerns with how we handle end of standard support and end of life posts.
