How to install Docker on Ubuntu 17.10 Artful Aardvark

Question

I followed the instructions on how to install Docker CE for Ubuntu. After I setup the repository, and then ran sudo apt-get update, I got the following error:

Err:12 https://download.docker.com/linux/ubuntu artful Release                                             
404  Not Found [IP: 2600:9000:201d:5000:3:db06:4200:93a1 443]

Reading package lists... Done
E: The repository 'https://download.docker.com/linux/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.

I'm using Ubuntu 17.10 (Artful Aardvark)

The following Docker GPG keys were added to my repo GPG keys file /etc/apt/sources.list

deb [arch=amd64] https://download.docker.com/linux/ubuntu zesty stable
# deb-src [arch=amd64] https://download.docker.com/linux/ubuntu zesty stable

Answer 1

Solution

Open your sources.list file as admin.

sudo emacs /etc/apt/sources.list

Find these two lines:

deb [arch=amd64] https://download.docker.com/linux/ubuntu artful stable
# deb-src [arch=amd64] https://download.docker.com/linux/ubuntu artful stable

And change the word artful to zesty in both lines. After the change, they should look like:

deb [arch=amd64] https://download.docker.com/linux/ubuntu zesty stable
# deb-src [arch=amd64] https://download.docker.com/linux/ubuntu zesty stable

Problem fixed, now install Docker CE with:

sudo apt-get update && sudo apt-get install docker-ce

Explanation

Th problem is that as of this writing, a release file for Ubuntu 17.10 Artful Aardvark is not available on Download Docker. Therefore, you have to use the release file for Ubuntu 17.04 (zesty) instead.

Answer 2

Ubuntu 17.10 is now supported in the edge release, so you can use

deb [arch=amd64] https://download.docker.com/linux/ubuntu artful edge

as well.
