记一次Ubuntu19无法安装docker源

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 InRelease
    Err:2 https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu eoan Release
    Not Found [IP: 218.104.71.170 443]
    Hit:3 http://cn.archive.ubuntu.com/ubuntu eoan InRelease
    Hit:4 http://cn.archive.ubuntu.com/ubuntu eoan-updates InRelease
    Hit:5 http://cn.archive.ubuntu.com/ubuntu eoan-backports InRelease
    Hit:6 http://cn.archive.ubuntu.com/ubuntu eoan-security InRelease
    Reading 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 stable
    deb [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:

    root@uduntu:~# apt search docker-ce

遇到这种问题我也觉得很头疼,在网上找了很多解决方法都是不行,有人都说是网络问题无法使用外网的源码库,我看到这个文章我都懵了,我还试过安装网易、阿里以及科大的源都不能更好的解决问题,其实这个很简单看一下阿里、科大和网易的他们的源码库是怎么往配置文件里面写的,然后比葫芦画瓢画一个不就完了

解决方法:

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:

    root@uduntu:~# apt-get  update
        Get:1 http://cn.archive.ubuntu.com/ubuntu eoan InRelease [255 kB]
        Get:2 http://cn.archive.ubuntu.com/ubuntu eoan-updates InRelease [88.4 kB]
        Hit:3 http://cn.archive.ubuntu.com/ubuntu eoan-backports InRelease
        Get:4 http://cn.archive.ubuntu.com/ubuntu eoan-security InRelease [92.9 kB]
        Get:5 https://download.docker.com/linux/ubuntu bionic InRelease [64.4 kB] 
        Get:6 https://download.docker.com/linux/ubuntu bionic/stable amd64 Packages [9,594 B] Fetched 511 kB in 11s (48.3 
    B/s) 
        Reading package lists... Done
    root@uduntu:~#

这样就好了,不报错了,再看看docker-ce这个安装包有没有:

    root@uduntu:~# apt search docker-ce
        Sorting... Done
        Full Text Search... Done
        docker-ce/bionic,now 5:19.03.4~3-0~ubuntu-bionic amd64 [installed]
        Docker: the open-source application container engine
        docker-ce-cli/bionic,now 5:19.03.4~3-0~ubuntu-bionic amd64 [installed,automatic]
        Docker CLI: the open-source application container engine
    root@uduntu:~#

OK这就搞定了!

好啦这次就到这里了,我继续更新我的大脑啦!!!
