按照各大网站以及个人习惯我会使用下面这种方法添加docker源：
root@ubuntu:~# sudo add-apt-repository "deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu $(lsb_release -cs) stable"然而使用上面这条命令给我带来了无尽的烦恼，甚至我都怀疑我是不是一个合格的linux工程师了，使用了这条命令提示以下错误:
ign:1 https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu eoan inreleaseerr:2 https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu eoan release404 not found [ip: 218.104.71.170 443]hit:3 http://cn.archive.ubuntu.com/ubuntu eoan inreleasehit:4 http://cn.archive.ubuntu.com/ubuntu eoan-updates inreleasehit:5 http://cn.archive.ubuntu.com/ubuntu eoan-backports inreleasehit:6 http://cn.archive.ubuntu.com/ubuntu eoan-security inreleasereading package lists... done e: the repository 'https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu eoan 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.下面是apt源文件中的内容：
deb [arch=amd64] https://download.docker.com/linux/ubuntu eoan stable# deb-src [arch=amd64] https://download.docker.com/linux/ubuntu eoan stabledeb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable发现是没有任何错误的，但是你会发现在使用apt更新时会出现各种各样报错，最终还是没有你想要的docker-ce安装包，还是无法安装：

在sources.list添加下面这一条就可以：
deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable更新apt源：
