$ sudo start jenkins
start: Job failed to start
  • same problem... There is nothing in /var/log/jenkins/jenkins.log But I can start jenkins with sudo /etc/init.d/jenkins start

Apparently the installed service is broken. But it works, as stated in my comment above, when you start the server with sudo /etc/init.d/jenkins start.


The following worked for me:

sudo rm /etc/init/jenkins.conf
sudo update-rc.d jenkins defaults
sudo service jenkins start


root@core:/# service jenkins start
* Starting Jenkins Continuous Integration Server jenkins                    [ OK ]
