Jenkins Debian Packages

https://pkg.jenkins.io/debian/

install

This is the Debian package repository of Jenkins to automate installation and upgrade. To use this repository, first add the key to your system:

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

Then add a Jenkins apt repository entry:

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

Update your local package index, then finally install Jenkins:

  sudo apt-get update
  sudo apt-get install fontconfig openjdk-11-jre
  sudo apt-get install jenkins

The apt packages were signed using this key:

pub   rsa4096 2020-03-30 [SC] [expires: 2023-03-30]
      62A9756BFD780C377CF24BA8FCEF32E745F2C3D5
uid                      Jenkins Project
