Debian系統中更新Jenkins主要有以下兩種方法：
sudo systemctl stop jenkins。wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -，創建/etc/apt/sources.list.d/jenkins.list文件并添加倉庫sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ /etc/apt/sources.list.d/jenkins.list'，然后更新包列表sudo apt update。sudo apt install jenkins。sudo systemctl enable --now jenkins。jenkins.war文件：sudo cp /usr/share/jenkins/jenkins.war /usr/share/jenkins/jenkins.war_bak。jenkins.war文件并替換：sudo cp /path/to/new/jenkins.war /usr/share/jenkins/。
