Ubuntu 14.04 and 16.04 image deprecation

What’s New

On February 15, 2022, the Ubuntu 14.04 and 16.04 Linux VM images used with our machine executor were deprecated, meaning there will be no new releases or support for these images moving forward. When these images reach end of life (EOL) on May 31, 2022, any pipelines that utilize Ubuntu 14.04 or 16.04 images will fail.

In order to prevent unexpected failures and enable you to begin moving to newer images, CircleCI’s Ubuntu 14.04 and 16.04 Linux virtual machine (VM) images will be temporarily unavailable in late March 2022 and late April 2022, and will become permanently unavailable as of May 31, 2022. During these temporary “brown-out” periods, if you are currently using either of these images, be sure to update your config with a newer Ubuntu machine image before the 14.04 and 16.04 images are removed at the end of May 2022.

For more information about how CircleCI will manage these updates, please see the Deprecating Ubuntu 14.04 and 16.04 blog post.
