这个命令会将 Docker 的官方软件仓库添加到系统的软件源列表中。它使用 add-apt-repository 命令将指定的源添加到 /etc/apt/sources.list 文件中,以便在系统中可以通过 apt-get 命令安装 Docker 软件包。
具体来说,该命令会将以下内容添加到 sources.list 文件中:
deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable
这个源指定了 Docker 官方软件仓库的 URL,并根据当前系统的发行版代号(通过 lsb_release -cs 命令获取)选择合适的版本。在添加了该源后,你就可以使用 apt-get 命令来安装 Docker 软件包了。

sudo add-apt-repository \ "deb [arch=amd64] https://download.docker.com/linux/ubuntu \ $(lsb_release -cs) \ stable"怎么设置仓库
这个命令是用来添加 Docker 官方仓库的。它会将以下内容添加到 `/etc/apt/sources.list` 文件中:
```
deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable
```
其中,`bionic` 是 Ubuntu 的发行版代号,这里使用的是 Ubuntu 18.04 LTS。
如果你要添加其他版本的仓库,可以将 `bionic` 替换为对应的发行版代号。例如,对于 Ubuntu 20.04 LTS,应该使用以下命令:
```
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
focal \
stable"
```
其中,`focal` 是 Ubuntu 20.04 LTS 的发行版代号。
The repository 'http://mirrors.aliyun.com/docker-ce/linux/ubuntu jammy InRelease' is not signed.
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.
