Jenkins 2.190.2 was released in 2019. It is no longer supported by the Jenkins update center. The list of plugin upgrades that are provided to Jenkins 2.190.2 by the Jenkins update center are not assured they will be compatible with 2.190.2. The [Jenkins update center site](https://updates.jenkins.io/) says: > At the moment, Jenkins weekly and LTS releases up to a year old are supported; anything older will receive update metadata for the oldest supported releases. Your options include: - Restore from backup and remain with the existing plugins and the existing Jenkins 2.190.2 install - Upgrade to the current Jenkins version (2.440.2) and current plugins
