"Package 'docker-ce' has no installation candidate" in 18.04

I'm following the official Docker installation guide for docker-ce on Ubuntu.

When I get to sudo apt install docker-ce I get E: Package 'docker-ce' has no installation candidate:

My first thought was that Docker haven't released a package for Bionic yet (it's very new) but when I searched for "install docker-ce ubuntu 18.04" I found a guide which seems 18.04 specific, and basically just gives exactly the same instructions - suggesting that it at least worked for the author:

Does anyone have any idea why this might not be working for me?

Run this if you want to install the docker-ce on Ubuntu 18.04:

sudo apt install apt-transport-https ca-certificates curl software-properties-common curl -fsSL | sudo apt-key add - sudo add-apt-repository "deb [arch=amd64] `lsb_release -cs` test" sudo apt update sudo apt install docker-ce 

To check if the installation ended successfuly, just run:

docker -v 

should output:

Docker version 18.06.1-ce, build e68fc7a 

From the same guide you referenced, you can use repository for 17.10 instead at this moment:

deb [arch=amd64] artful stable 

And all docker-ce dependent packages will be resolved from the ubuntu bionic repository. Check the Docker documentation for more info. No compatibility issues to worry about :)

Docker 18.06 has been updated to bionic repository, this workaround is not required anymore!

Some of the guides jumped the gun; docker-ce is not available for Ubuntu 18.04 yet at the time of this post. You can check the list of supported versions here.

That same guide you linked to suggested installing docker.io; this is what I did. It's a workaround until docker-ce supports 18.04.

Following the steps here in the Docker documentation worked for me. I just had to change stable to test in this command

sudo add-apt-repository \ "deb [arch=amd64] \ $(lsb_release -cs) \ stable" 

I had the same issue, here is how I fixed it:

$ sudo snap install docker $docker -v Docker version 18.06.1-ce, build e68fc7a $sudo docker version Client: Version: 18.06.1-ce API version: 1.38 Go version: go1.10.4 Git commit: e68fc7a Built: Tue May 7 18:01:43 2019 OS/Arch: linux/386 Experimental: false Server: Engine: Version: 18.06.1-ce API version: 1.38 (minimum version 1.12) Go version: go1.10.4 Git commit: e68fc7a Built: Tue May 7 18:01:44 2019 OS/Arch: linux/386 

If you are getting the error, Package 'docker-ce' has no installation candidate, then use this:

sudo add-apt-repository "deb [arch=amd64] $(lsb_release -cs) stable edge test" 

Snap package of docker will be easily install able on Ubuntu 19.04 (Disco) and it worked for me.

Check out the documentation for it here :

By Executing the following commands we can install docker

 curl -fsSL get.docker.com | CHANNEL=stable sh sudo apt install docker-ce sudo apt-get install docker-ce docker-ce-cli containerd.io
