一、报错描述

在ubuntu 22.01上执行在线安装docker命令时出现E: Package 'docker-ce' has no installation candidate错误。

<code>sudo apt install docker-ce docker-ce-cli containerd.io

下面是详细报错信息

root@ubuntu:# sudo apt install docker-ce docker-ce-cli containerd.io

Reading package lists... Done

Building dependency tree... Done

Reading state information... Done

Note, selecting 'moby-containerd' instead of 'containerd.io'

Package docker-ce is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source

However the following packages replace it:

moby-engine:armhf moby-cli:armhf moby-cli:arm64 moby-engine:arm64 moby-cli moby-engine

Package docker-ce-cli is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source

However the following packages replace it:

moby-cli:armhf moby-cli:arm64 moby-cli

E: Package 'docker-ce' has no installation candidate

E: Package 'docker-ce-cli' has no installation candidate

E: Unable to locate package docker-compose-plugin

二、问题分析

这种报错信息，很明显是说明apt的源设置的不对。

三、解决步骤

安装阿里云证书，并配置阿里云的docker源

# 安装阿里云gpg证书

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add

# 在指定目录下新建docker.list文件，添加阿里云镜像源

cd /etc/apt/sources.list.d

sudo touch docker.list

sudo chmod 666 docker.list

sudo echo "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" > docker.list

修改完成之后需要执行如下命令才会生效

# 更新软件源

sudo apt-get update && sudo apt-get upgrade

重新执行命令安装

# 安装最新Docker

sudo apt install docker-ce docker-ce-cli containerd.io

下面是安装过程
