Beginning March 28, 2023, 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 April 5, 2023. Administrators of Linux systems must install the new signing keys on their Linux servers before installing Jenkins Jenkins weekly 2.397 or Jenkins LTS 2.387.2.
