Thanks for reporting. You should follow the reported problem in the following issue: Jenkins 2.545 AlmaLinux package forces Java 17 dependency, breaks startup requiring Java 21 · Issue #729 · jenkinsci/packaging · GitHub
The packages and Docker images have been fixed yesterday (Wednesday 07 January 2026).
An important note though: “friend don’t let friend use latest in their Docker tags”. We strongly suggest you to pin your tag version (for instance: “2.544-jdk17”) and add an automatic upgrade process (with or without human review) to ensure you always have a reproducible state (and avoid bad surprises like this one).
