ubuntu 22.04安装jenkins，总是报错

The repository 'https://pkg.jenkins.io/debian-stable binary/ Release' is not signed.

查阅了相关资料后，发现如果安装新版本的话，需要更新signing key

Beginning March 28, 2023, the Jenkins weekly releases will use new repository signing keys for the Linux installation packages. The same change will be made in Jenkins LTS releases beginning April 5, 2023. Administrators of Linux systems must install the new signing keys on their Linux servers before installing Jenkins Jenkins weekly 2.397 or Jenkins LTS 2.387.2.

Debian/Ubuntu LTS release 执行如下命令：

$ curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io-2023.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

Debian/Ubuntu weekly release

$ curl -fsSL https://pkg.jenkins.io/debian/jenkins.io-2023.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 binary/ | sudo tee \
  /etc/apt/sources.list.d/jenkins.list > /dev/null
