问题描述
我正在尝试在the official installation guide之后在Ubuntu 64计算机上安装Docker。
可悲的是，Ubuntu似乎无法找到docker-ce软件包。有任何解决方案或至少跟踪发生的事情的想法吗？
这里为您提供一些细节…
$ uname --all; sudo grep docker /etc/apt/sources.list; sudo apt-get install docker-ce
Linux ubuntu 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable.
# deb-src [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable.

最佳思路
Ubuntu 20.04(Focal)
sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"
Ubuntu 19.10(Eoan)
sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu eoan stable"
Ubuntu 19.04(Disco)
sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu disco stable"
Ubuntu 18.10(宇宙)
sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic test"
Ubuntu 18.04(仿生)
sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"
Ubuntu 17.10
docker-ce软件包可在官方docker(Ubutu Artful)存储库上使用，使用以下命令进行安装：
sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu artful stable"
Ubuntu 16.04
您可以按照以下步骤在Ubuntu上安装docker-ce：
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable"
运行以下命令：
sudo apt update
apt-cache search docker-ce
样本输出：
docker-ce - Docker: the open-source application container engine
安装docker-ce：
对于Ubuntu 16.04，您需要运行sudo apt update。对于Ubuntu 18.04及更高版本，add-apt-repository将自动执行apt update：
sudo apt install docker-ce

次佳思路
对于使用Ubuntu 17.10(熟练的)并且遇到此问题的任何人：
从https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/
To install Docker CE, you need the 64-bit version of one of these Ubuntu versions:
Artful 17.10 (Docker CE 17.11 Edge only)
Zesty 17.04
Xenial 16.04
(LTS) Trusty 14.04 (LTS)
和：
To add the edge or test repository, add the word edge or test (or both) after the word stable in the commands
因此，如果您使用的是Ubuntu 17.10(精巧版)，则需要添加以下内容：
$ sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable edge"
注意添加了”edge”字。如果您之前没有”edge”就已经运行过此命令。您可以在/etc/apt/sources.list上编辑source.list文件。之后，照常刷新并安装docker-ce：
sudo apt-get update
sudo apt-get install docker-ce
