Reading package lists... Done
E: The repository 'https://download.docker.com/linux/ubuntu focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
答案1:
截至今天为止,Ubuntu 20.04 LTS focus的发行文件尚不可用。
您可以在Docker社区码头上更改以下命令:
$ sudo add-apt-repository
"deb [arch=amd64] https://download.docker.com/linux/ubuntu
$(lsb_release -cs)
stable"
到
$ sudo add-apt-repository
"deb [arch=amd64] https://download.docker.com/linux/ubuntu
bionic
stable"
还请确保在安装docker之前从/etc/apt/sources.list中删除以下条目(如果存在)
deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable
答案2:
另一个选项是安装ubuntu提供的Docker版本:
sudo apt install docker.io
对于Focal,docker.io当前(2020年4月24日)的版本为19.03.8-0ubuntu1,对于大多数Docker工作负载而言这是令人满意的新功能。
