Why it’s so difficult here to install Jenkins?
Hi @uwithnishad,
Thanks for highlighting this. I will check from my end and get back to you.

Hi @uwithnishad,
I tried it and didn’t face any problem.
Regards,
In the shared screenshots, I used the dnf tool to install the Jenkins package, but it will work the same for yum utility tool.
Regards,
It did not work for yum but I will try to use dnf as you did then will let you know.
Thanks.
Hi @uwithnishad,
Did you add the repository? Without adding that software repositories to the server, you can’t install Jenkins. Unless it’s already available in the existing pre-configured repositories.
Yes. did everything as you mentioned above but still it got failed.
sudo dnf install jenkins

Finally, it’s done. I tried a different approach and then succeeded.
Thanks.
Great, finally it worked for you. 
How can I connect you directly? Please advise. a couple of questions to ask.
Thanks.
I spent a whole day trying to figure this thing out. Turns out the version of Java i was installing was not good. I installed Java-11-openjdk (the one installed during the jenkins course.)
I removed that, installed the Java-17-opendjk and it worked.
Here is my script
sudo yum install epel-release -y
sudo yum install java-17-openjdk -y
sudo yum install wget -y
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo --no-check-certificate
sudo rpm --import http://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key
sudo yum update -y
sudo yum install jenkins -y

I “solved” this by installing java v11 instead of v17
sudo yum install java-11-openjdk -y.
