Docker 安装问题 (ubuntu 20.04 LTS) - E：存储库'https://download.docker.com/linux/ubuntu Release'没有发布文件

Question

我在虚拟机上安装docker时遇到问题。我遵循了以下步骤:

1。Docker的旧版本被称为Docker, Docker。Io，即docker-engine。如果安装了这些，请卸载:

sudo apt-get remove docker docker-engine docker.io containerd runc

2。更新apt包索引

sudo apt-get update

3。安装包以允许apt通过HTTPS使用存储库:

sudo apt-get install 
apt-transport-https 
ca-certificates 
curl 
gnupg 
lsb-release

4。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

5。使用以下命令设置稳定库:

echo 
"deb [arch=amd64 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

6。更新apt包索引

sudo apt-get update

此时—在输入sudo apt-get update之后—我得到以下错误

root@xxx:/home/xxx# sudo apt-get update

/etc/apt/sources.list.d/docker.list内容

deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] download.docker.com/linux/ubuntu focal stable

有办法修复它吗?

Answer 1

确保/etc/apt/sources.list.d/docker.list的内容与文档中项目#3命令的输出相对应。

在我写这篇文章的时候，在我的Ubuntu 20.04 LTS上执行这个命令会导致docker的以下内容。列表文件:deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu focal stable

似乎和你的不一样。

Answer 2

我也有同样的问题，

我的码头工人。列表文件

deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu      jammy stable

/ubuntu和jammy stable之间有太多空格…一旦去掉额外的空间，sudo apt-get update就可以工作了。
