sudo sh -c 'echo deb https://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'

Update the apt package list to include the newly added repository.

sudo apt-get update

Finally, install Jenkins using the following command

sudo apt-get install jenkins

Step 4: Configure Jenkins

After the installation is complete, you can access the Jenkins web interface using your web browser. To do this, open your web browser and go to http://localhost:8080/.

You will be prompted to enter the initial admin password. The password can be found in the following file

/var/lib/jenkins/secrets/initialAdminPassword

Copy and paste the password into the web interface and click "Continue."

Next, select "Install suggested plugins" and wait for the installation to complete.

After the plugins are installed, you will be asked to create an admin user. Fill in the required fields and click "Save and Continue."

Finally, you can customize your Jenkins installation by selecting the plugins you want to use and configuring the global settings. Once you're done, click "Save and Finish" to complete the setup.
