Photon OS 2.0 – End of Support
As of January 2023, Photon OS 2.x will no longer receive security fixes, package upgrades, bug fixes, or feature enhancements. Consequentially, Photon 2.x base container images will also no longer be published on Docker Hub. Upgrade to the latest version of Photon OS is highly recommended for all users of Photon OS 2.x.
