Installing the latest version of Jenkins

To install the latest version of Jenkins, follow these steps in sequence:

1. Add the repository key to the system using the following command:

        - https://pkg.jenkins.io/debian/jenkins-ci.org.key | \
        sudo apt-key add - 

1. You should get an output of OK. Next, append the Debian package repository address using the following command:

        echo deb http://pkg.jenkins.io/debian binary/ | \
        sudo tee /etc/apt/sources.list.d/jenkins.list 

1. Update the package index:

1. Now, install Jenkins using the following command:

        sudo apt-get install jenkins
