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

我的第一个想法是 Docker 还没有发布 Bionic 包（它很新）但是当我搜索“安装 docker-ce ubuntu 18.04”时，我发现了一个指南，它似乎是 18.04 特定的，基本上只是给出了完全相同的说明- 建议它至少对作者有用：

https://linuxconfig.org/how-to-install-docker-on-ubuntu-18-04-bionic-beaver

有谁知道为什么这可能对我不起作用？

Answer 1

如果要安装运行此docker-ce有关Ubuntu 18.04：

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 `lsb_release -cs` test"
sudo apt update
sudo apt install docker-ce

要检查安装是否成功结束，只需运行：

docker -v

应该输出：

Docker version 18.06.1-ce, build e68fc7a

Answer 2

根据您引用的同一指南，此时您可以改用 17.10 的存储库：

deb [arch=amd64] https://download.docker.com/linux/ubuntu artful stable

并且所有docker-ce依赖包都将从 ubuntubionic存储库解析。查看Docker 文档以获取更多信息。无需担心兼容性问题:)

2018-07-19 更新

Docker 18.06 已更新到bionic存储库，不再需要此解决方法！

Answer 3

一些导游跳了枪；在撰写本文时，docker-ce 尚不可用于 Ubuntu 18.04。您可以在此处查看支持的版本列表。

您链接到建议安装 docker.io 的同一指南；这就是我所做的。这是一种解决方法，直到 docker-ce 支持 18.04。

Answer 4

按照Docker 文档中的步骤操作对我有用。我只stable需要test在此命令中更改为

sudo add-apt-repository \ 
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"

我遇到了同样的问题，这是我修复它的方法：

$ sudo snap install docker

$docker -v
