Question posted in 
I’m installing Jenkins on AWS EC2 CentOS instance.
I’m following this tutorial for installation – https://medium.com/@itsmattburgess/installing-jenkins-on-amazon-linux-16aaa02c369c.
I’m getting the below error while installing:
Downloading packages:
warning: /var/cache/yum/x86_64/7/jenkins/packages/jenkins-2.232-1.1.noarch.rpm: Header V4 RSA/SHA512 Signature, key ID 45f2c3d5: NOKEY:00 ETA
Public key for jenkins-2.232-1.1.noarch.rpm is not installed
jenkins-2.232-1.1.noarch.rpm | 63 MB 00:01:49
Where am I getting wrong?

Issue got resolved. Instead of the command "sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo" i used "sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo "and it was working. Than's every for viewing my question and taking time to answer it.
Updated: They’ve updated their key URL to the following – import this key as part of the setup instead and the
yum installcall should function without issues and not require disabling the gpg check:https://pkg.jenkins.io/redhat/jenkins.io.key
Original answer: I’ve also been hitting this. The team has apparently updated their key, but haven’t updated the docs or published the new public key component and the one located at http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key isn’t valid any longer. For now you can run a
yum installwith GPG check disabled just to get past the initial install Jenkins:Once they’ve published the new public key, you’ll want to import it with the
rpm --import [url]call per usual so thatyum updatewill work as expected.Jenkins is changing their signing keys again.
Beginning with LTS
2.387.2and weekly2.397, releases will be signed with a new GPG key.The correct public key can be found on the page for Jenkins Redhat Packages and in Jenkins installation handbook. Just run the command below to import it:
