这个问题是由于缺少APT Key导致的。APT Key是用于验证软件包的数字签名的密钥。你需要获取缺失的APT Key,并将其添加到系统中,以便APT可以验证软件包的数字签名。你可以通过以下命令获取缺失的APT Key: ``` sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5 3B4FE6ACC0B21F32 ``` 这将从Ubuntu的密钥服务器上下载并添加缺失的APT Key。完成后,再次运行更新命令应该就不会出现这个错误了。

W: GPG error: http://packages.ros.org/ros/ubuntu bionic InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F42ED6FBAB17C654

这个错误是由于缺少ROS存储库的公钥导致的。你可以使用以下命令来解决这个问题: ``` sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key F42ED6FBAB17C654 ``` 运行以上命令将下载并安装ROS存储库的公钥。然后,再次尝试更新软件源和安装ROS: ``` sudo apt-get update sudo apt-get install ros-melodic-desktop-full ```

N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.

这个错误是因为缺少 Jenkins 仓库的公钥。您可以按照以下步骤导入公钥并解决问题: 1. 打开终端。 2. 下载 Jenkins 的公钥。输入以下命令并按回车: ``` wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add - ``` 3. 重新运行 `sudo apt update` 命令以更新软件包列表。 现在,您应该能够成功更新软件包列表,然后继续安装 Jenkins。请尝试执行之前的步骤,并告诉我是否还遇到问题。
