We updated three plugins for jenkins. After they were updated jenkins will not start. We get jenkins.service: main process exited, code=exited, status=5/NOTINSTALLED and jenkins.service: main process exited, code=exited, status=1/FAILURE. Any ideas what this error could be or perhaps suggest a starting place to find the issue?
It turns out the issue was that somehow installing the plugin update removed JAVA from the system path.
