18.04 版中出现“软件包‘docker-ce’没有安装候选项”

我正在跟进官方 Docker 安装指南适用于 Ubuntu 上的 docker-ce。

当我到达时，sudo apt install docker-ce我得到E: Package 'docker-ce' has no installation candidate：

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

我的第一个想法是 Docker 还没有为 Bionic 发布一个软件包（它很新），但是当我搜索“安装 docker-ce ubuntu 18.04”时，我发现了一个似乎特定于 18.04 的指南，并且基本上只是给出了完全相同的说明 - 表明它至少对作者有用：

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

有谁知道为什么这可能不适合我？

答案1

如果要安装，请运行此docker-ce命令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

答案2

从您引用的同一指南中，您现在可以改用 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 ubuntu 存储库中解析bionic。检查Docker 文档了解更多信息。不用担心兼容性问题 :)

Docker 18.06 已更新至bionic存储库，不再需要此解决方法！

答案3

我遇到了同样的问题，下面是我修复的方法：

$ sudo snap install docker

$docker -v

Docker version 18.06.1-ce, build e68fc7a


$sudo docker version

答案4

按照步骤Docker 文档中对我有用。我只需要在这个命令中更改stable为test

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