我不会写过我写的，但发现了通过互联网解决的类似问题。我已经搜索了几乎所有的Q＆amp;一个站点，并且与4小时前完全相同的位置。我遵循文档，将docker ce安装在我的Ubuntu 17.10系统上。但是，当我尝试运行sudo apt-get update时，我在控制台上会出现以下错误：
Ign:1 http://ppa.launchpad.net/mc3man/xerus-media/ubuntu artful InRelease
Get:2 http://security.ubuntu.com/ubuntu artful-security InRelease [78.6 kB]
Hit:3 https://download.docker.com/linux/ubuntu artful InRelease
Hit:4 http://in.archive.ubuntu.com/ubuntu artful InRelease
Err:5 http://ppa.launchpad.net/mc3man/xerus-media/ubuntu artful Release
404 Not Found
Get:6 http://in.archive.ubuntu.com/ubuntu artful-updates InRelease [78.6 kB]
Get:7 http://in.archive.ubuntu.com/ubuntu artful-backports InRelease [72.2 kB]
Reading package lists... Done
E: The repository 'http://ppa.launchpad.net/mc3man/xerus-media/ubuntu artful 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.
，不用说，我无法继续使用Docker。我该如何解决？P.S.，我尝试编辑我的资源。清单文件，但它已阅读，我无法保存更改。另外事实，我注意到在http://ppa.launchpad.net/mc3man/xerus-media/ubuntu/上，发行文件位于Dist/Xenial文件夹中。
。请帮助我解决此问题。
编辑：这是我的来源。清单文件以添加信息。

您有两个问题混合在一起，因为初学者可以在Xerus-Media上工作
cd /etc/apt
grep -r xerus *
现在编辑包含Xerus
的文件sudo vi /etc/apt/either_sources.list_or_a_file_in_subdir
删除提到的行
http://ppa.launchpad.net/mc3man/xerus-media/ubuntu artful Release
添加这些行
deb http://ppa.launchpad.net/mc3man/xerus-media/ubuntu xenial main
deb-src http://ppa.launchpad.net/mc3man/xerus-media/ubuntu xenial main
保存该文件并确认您不再看到提到Xerus-Media
的错误sudo apt-get update
现在进入Docker问题... Ubuntu的Docker软件包已运送到Xenial ...所以让我们看看您拥有的...做什么
cd /etc/apt
grep -r docker *
现在编辑像
中提到docker的文件sudo vi /etc/apt/sources.list
现在编辑行
deb [arch=amd64] https://download.docker.com/linux/ubuntu artful stable
它的条目应该看起来像这样
deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable
（是的，Xenial，还可以，您仍然会得到最新的Docker）现在让我们看看您已经安装了哪个Docker软件包...发行此
dpkg -l | grep docker
您应该看到此
ii docker-ce 17.09.0~ce-0~ubuntu amd64 Docker: the open-source application container engine
现在进行更新
sudo apt-get update && sudo apt-get dist-upgrade
您现在已锁定并加载了吗？如果没有，我们可以继续战斗
