Beginning December 23, 2025, the Jenkins weekly releases will use new repository signing keys for the Linux installation packages. The same change will be made in Jenkins LTS releases beginning January 21, 2026.

Technical details are described in [pkg.jenkins.io/release.ci.jenkins.io] Jenkins Packaging GPG key expires on the 26 March 2026 · Issue #4922 · jenkins-infra/helpdesk · GitHub.

Instructions will be included in the changelog for the release and in a blog post. Conversations about the change can be posted as replies to this topic.

The new GPG key has the following identity:

pub   rsa4096 2025-12-22 [SC] [expires: 2028-12-21]
      5E386EADB55F01504CAE8BCF7198F4B714ABFC68
uid                      Jenkins Project

I would like to point out, that the given command example for debian/ubuntu adds the weekly release repository. So anyone on LTS could find themselves ending up on using 2.547 instead of 2.541.1.
