回答: 这个错误是因为软件源没有签名导致的。在安装ROS时,你需要添加ROS软件源到sources.list文件中。你可以使用以下命令将ROS软件源地址添加到sources.list文件中:sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'。然后,运行sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654来添加ROS软件源的公钥。这样就可以解决这个问题了。

As an AI language model, I don't have access to the system logs so I cannot determine the exact cause of this issue. However, this error message typically means that the package repository you're trying to access is not properly signed or authenticated.
To fix this issue, you can try the following steps:
1. Check if your system's date and time are correct. An incorrect date and time can cause issues with package authentication.
2. Try to update the package list again using the following command:
```
sudo apt-get update
```
3. If the error persists, you can try changing the package repository by editing the `/etc/apt/sources.list` file. You can try using a different mirror, such as the official Docker repository:
```
deb [arch=amd64] https://download.docker.com/linux/ubuntu jammy stable
```
4. If none of the above steps work, you can try manually importing the GPG key for the repository using the following command:
```
sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys <KEY_ID>
```
Replace `<KEY_ID>` with the ID of the GPG key for the repository. You can usually find this on the repository's website.
If none of these steps work, you can try reaching out to the maintainers of the repository for further assistance.

这个错误看起来是您的Ubuntu系统更新源的问题。其中的一些源似乎已经过期或尚未更新。
您可以尝试等待一段时间,然后再次尝试运行更新命令。通常情况下,这些更新源会在一段时间后自动更新并恢复正常。
如果问题仍然存在,请尝试使用其他的Ubuntu更新源,例如清华大学的更新源(http://mirrors.tuna.tsinghua.edu.cn/ubuntu/)或中科大的更新源(http://mirrors.ustc.edu.cn/ubuntu/)。
您可以按照以下步骤更改更新源:
1. 打开终端并输入以下命令以备份当前的更新源列表:
```
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
```
2. 使用您选择的更新源替换原始更新源。例如,如果您要使用清华大学的更新源,请使用以下命令替换更新源:
```
sudo sed -i 's/archive.ubuntu.com/mirrors.tuna.tsinghua.edu.cn/g' /etc/apt/sources.list
```
3. 运行以下命令以更新软件包列表:
```
sudo apt-get update
```
如果更新成功,则应该没有错误消息。
4. 最后,您可以尝试重新运行您的Docker安装命令以重新安装Docker。
如果问题仍然存在,请提供更多信息,以便我更好地帮助您解决问题。
