I'm trying to install Docker on a Ubuntu 64 machine following the official installation guide.

Sadly Ubuntu seems it is not able to locate the docker-ce package. Any idea to fix it or at least to track what is happening ?

Here some details for you...

$ uname --all; sudo grep docker /etc/apt/sources.list; sudo apt-get install docker-ce

Linux ubuntu 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

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

Reading package lists... Done

E: Unable to locate package docker-ce

    Did you run apt-get update after adding the repo?

Add Docker's official GPG key:

sudo apt update
sudo apt install ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

Run the following:

sudo apt update
apt-cache search docker-ce

sample output:

docker-ce - Docker: the open-source application container engine

Install docker-ce:

sudo apt install docker-ce

To check the available and permitted Ubuntu codenames:

curl -sSL  https://download.docker.com/linux/ubuntu/dists/ |awk -F'"' 'FNR >7 {print $2}'

sample output (Results may be different after the directory updates):

focal/

    way better than docs.docker.com/engine/installation/linux/docker-ce/ubuntu Commented Jul 15, 2017 at 20:59

    It's worth mentioning that for Ubuntu 17.10, the step 3 would be: sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu artful stable"

    @GAD3R that's a good answer. perhaps bull-headed of me, want to install with snap -- if do-able. (I mean, it installs, but then...etc. something about apparmor.) I'll come back and try this at some point -- I'm sure it works :)

    The instructions for 17.10 also worked for me in 18.04, when the official docker-ce install instructions did not. Maybe not recommended though, since it's from the artful repo?

For anyone who is using Ubuntu 17.10 (artful) and having this problem:

From https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/

To install Docker CE, you need the 64-bit version of one of these Ubuntu versions:

Artful 17.10 (Docker CE 17.11 Edge only)

Zesty 17.04

Xenial 16.04

(LTS) Trusty 14.04 (LTS)

and:

To add the edge or test repository, add the word edge or test (or both) after the word stable in the commands

So if you are using Ubuntu 17.10 (artful), you need to add this:

$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable edge"

Noticing "edge" word is added. If you already ran this command before without "edge". You can edit the source.list file at /etc/apt/sources.list. After that, refresh and install docker-ce as usual:

sudo apt-get update
sudo apt-get install docker-ce
5

Try using:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

$  sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

$ sudo apt-get update
$  sudo apt install docker.io

  • when asked for version docker version, it gave hint to use $sudo apt install docker.io.. that ran successfully.

  • @HydTechie, The docs says that the old docker versions should be uninstalled, docker.io being one of the older versions: docs.docker.com/install/linux/docker-ce/ubuntu/…

Looks like docker will be in official repository after December docker-ce release (stable). Then this repository:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu artful stable"

should work. Meanwhile there should be soon available edge release on

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu artful edge"

But its not available now yet. But v17.11.0-ce-rc4 was released yesterday, so i would expect it any day now.

So for now I used package from 17.04 repo as GAD3R is suggesting.

link to github issue.

None of the above worked for me.

I removed docker completely, then went and manually removed the docker files in /var.

Reinstalled and running perfectly afterwards.

    FYI for 19.04 'disco' repo does not have docker-ce, you have to use bionic until it gets added. sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"
