| Doing a clean install of Jenkins fails, presumably because of the corrupted version of the workflow multibranch plugin (2.9.1). Steps to reproduce:
- Install Jenkins (2.19.2) on Ubuntu 16.10 server from the official Jenkins debian repository
- Run the setup procedure and install the recommended plugins
- Restart Jenkins
Expected: for Jenkins to successfully start Actual: Jenkins fails to start with the following exceptions: ```

``` Workaround:
I'm not sure, but the fact that the workflow multibranch plugin page still lists 2.9.1 as the "Latest Release", even though 2.9.2 is released and the change notes say that 2.9.1 is corrupted might be related: https://wiki.jenkins-ci.org/display/JENKINS/Pipeline+Multibranch+Plugin |
