Before proceeding with the installation of the Jenkins, we will update the Ubuntu 22.04 repository to get the latest updates of all the packages available in the repository:

$ sudo apt update

Now the jenkins package needs the JDK package, so we will install the JDK package:

$ sudo apt install default-jdk -y

Now we will import the GPG key of the Jenkins from its official website using the curl command:

$ curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo tee \
  /usr/share/keyrings/jenkins-keyring.asc > /dev/null

$ echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] \
  https://pkg.jenkins.io/debian-stable binary/ | sudo tee \
  /etc/apt/sources.list.d/jenkins.list > /dev/null

When it is successfully added to the default repository of the Ubuntu 22.04, we will update the repository using the command:
