回答: 您想要知道如何在Ubuntu上安装Docker CE版本19.03。根据引用和引用的信息，以下是安装Docker CE 19.03的步骤:

1. 首先，确保您的系统已更新并安装了必要的软件包。

sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common

2. 添加Docker的官方GPG密钥。

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

3. 添加Docker的APT存储库。

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

4. 安装Docker CE。

sudo apt-get update
sudo apt-get install -y docker-ce docker-ce-cli containerd.io

根据引用，如果您想安装其他版本的Docker CE，您可以使用以下命令列出可用版本并选择特定版本进行安装:

sudo apt-get update
apt-cache madison docker-ce
sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io

请注意，`<VERSION_STRING>`应替换为您想要安装的具体版本号。

希望这些步骤可以帮助您在Ubuntu上成功安装Docker CE 19.03。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
