在Ubuntu 18.04 LTS中安装Jenkins失败（无法启动LSB：在引导时启动Jenkins。）

[根本原因]

• Ubuntu 18.04 LTS使用Java 9作为默认Java
• Jenkins 2.107.2仍使用Java 8

[解]

• 在安装Jenkins之前先安装Java 8

  sudo add-apt-repository ppa:webupd8team/java

  sudo apt install oracle-java8-installer
  wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -
  sudo apt-add-repository “deb https://pkg.jenkins.io/debian-stable binary/”
  sudo apt-get update
  sudo apt install jenkins
