Hi , I am trying to install Jenkins on OCI instance using the below steps from URL - [Linux](https://www.jenkins.io/doc/book/installing/linux/#red-hat-centos) At step to start jenkins, i am getting below error . I have executed all the commands as root user. Please guide me in this issue. [root@scheduler ~]# sudo systemctl start jenkins Job for jenkins.service failed because the control process exited with error code. See “systemctl status jenkins.service” and “journalctl -xe” for details. Thanks in advance ---

Hello @MoreshToraskar and welcome to this community 👋 Could you launch the proposed commands `systemctl status jenkins.service` and `journalctl -xe` and paste the logs in here? Thanks. ---

Thanks. At first glance, it looks like a permission problem: ```auto Failed to delete dirs /var/lib/jenkins/%C/jenkins/war/scripts/yui/base/base-min.css ``` But does that directory even exist? What is that `%C`? Why do we have `jenkins` twice in the path? Would you mind uninstalling Jenkins and restart from `sudo yum install jenkins` ? ---

Hi @poddingue I was able to resolve the installation issue with help of a colleague in our team. The issue was less memory on the server and installation issues. Thanks for your help! ---

I would never have guessed memory could have been part of your problem. 😉 Thanks a lot for your feedback, and happy to see you solved your problem. 🙏
