An update on upki

In December 2025, Canonical announced a plan to develop a universal Public Key Infrastructure called upki. Jon Seager has published an update about the project with instructions on trying it out. > In the few weeks since we announced upki, the core revocation engine has been established and is now functional, the CRLite mirroring tool is working and a production deployment in Canonical's datacentres is ongoing. We're now preparing for an alpha release and remain on track for an opt-in preview for Ubuntu 26.04 LTS.
