Selective Support

On September 30, 2018 at 11:59 PM UTC Cucumber Linux 1.0 will move from the full support stage of its lifecycle to the selective support stage. This is happening because upstream support is ending for at least one of the core packages. During selective support, we will continue to provide security updates for as many packages as possible; however, it will no longer be possible to provide security updates for the packages that are now unsupported upstream. For more details, see the Cucumber Linux support policy at

The following packages will no longer be supported on Cucumber Linux 1.0 effective at 12:00 AM UTC on the indicated date. All other packages will continue to be supported until the end of life date (November 30, 2018).

End of Life

On November 30, 2018 at 11:59 PM UTC Cucumber Linux 1.0 will reach its end of life. Once at its end of life, Cucumber Linux 1.0 will not receive any further updates for any reason, including security fixes for packages that are still supported upstream. It is therefore very important that users of Cucumber Linux 1.0 upgrade their systems to a supported version before this date.

Upgrade Path

The recommended upgrade path for users of Cucumber Linux 1.0 is to upgrade to Cucumber Linux 1.1, released on April 4, 2018. Cucumber Linux 1.1 will be fully supported through December 31, 2019 and selectively supported into 2020. In order to avoid missing any important security patches, all users should idealy upgrade their systems before September 30, 2018 and should definitely upgrade by November 30, 2018 at the absolute latest.
