Scientific Linux 7 reaches end of life

While the end of support for CentOS 7, which happened on June 30, is significant, it is also worth taking a moment to reflect on the end of Scientific Linux 7, which has also just occurred. Scientific Linux was once a popular RHEL rebuild supported by Fermilab, CERN, DESY, and ETH Zurich. Development of Scientific Linux stopped with SL7, with the labs switching to CentOS thereafter, but the SL7 release was supported through to the bitter end. Thanks are due to all who built and supported Scientific Linux; you provided a useful and stable platform for many years.

Hello,


Following the upstream release cycle:


Scientific Linux 7 reached End of Life June 30, 2024.

After this date no additional updates will be published for Scientific Linux 7.

Specifically, no security updates for SL7 will be published after June 30,
2024.

After June 30 2024:

- The installation trees will be moved into the 'obsolete' directory.

- Kickstart and yum operations against the old repository locations will no
  longer work.

- the official docker images for SL7 (docker pull sl:7) will be retired

-- A copy of the final docker image will be placed in the 'obsolete'
   directory.

The files themselves will remain available under the 'obsolete' directory.[1]

Users of Scientific Linux 7 should evaluate options for migrating to an
actively maintained operating system.

Fermilab recommends Almalinux[2] at this time.

CentOS Stream[3] is also available.
