Can't install Jenkins on Ubuntu 24.04 LTS

Hey, folks,

I followed these steps to install Jenkins on Ubuntu but the installation did not finish successfully.

Here is the “error” I’m seeing. Can anyone assist?

Could not execute systemctl: at /usr/bin/deb-systemd-invoke line 148.

You should use
journalctl -u jenkins
to see the actual output of the service. It will most likely tell you what the problem is.

Thank you!

Here’s the output of this command:

I wasn’t able to paste it here. More than 32000 chars.

I think I managed to resolve it. I have apache installed and it’s using the same port 8080.

I searched in Google and found this command:

image

It works now.

Thank you.

The problem is still here.

I changed the default port in the /etc/default/jenkins file to 8090 and restarted my machine however Jenkins is still looking for 8080.

How to resolve this?

UPDATE: found a solution. I modified the port in this file /usr/lib/systemd/system/jenkins.service and it worked.
