Cannot install Docker on Debian Jessie - docker

Question

Despite trying both the official installation mechanism using the new apt repo described here, as well as the curl -fsSL https://get.docker.com/ | sh route, I still get E: Unable to locate package docker-engine from APT when I try to apt-get install docker-engine.
My versions are:
$ uname -a
Linux blah 4.5.5-x86_64-linode69 #3 SMP Fri May 20 15:25:13 EDT 2016 x86_64 GNU/Linux
$ lsb_release -c
Codename: jessie
$ cat /etc/debian_version
8.5
$ cat /etc/apt/sources.list
deb http://ftp.uk.debian.org/debian/ stable main contrib non-free
deb-src http://ftp.uk.debian.org/debian/ stable main
deb http://security.debian.org/ stable/updates main
deb-src http://security.debian.org/ stable/updates main
deb http://http.debian.net/debian wheezy-backports main
The only file in my /etc/apt/sources.list.d is docker.list which contains:
deb https://apt.dockerproject.org/repo debian-jessie main
apt-cache policy docker-engine doesn't find it either:
apt-cache policy docker-engine
N: Unable to locate package docker-engine
How might I resolve this?

Answer 1

Edit your sources.list and change the following line from:
deb http://http.debian.net/debian wheezy-backports main
to
deb http://ftp.debian.org/debian jessie-backports main
Update and install docker:
apt-get update
apt-get install docker.io
Edit
To install a specific version of docker-engine download the .deb package from here, e,g the latest one is docker-engine_1.9.1-0~jessie_amd64.deb:
wget https://apt.dockerproject.org/repo/pool/main/d/docker-engine/docker-engine_1.9.1-0~jessie_amd64.deb
sudo apt-get update
dpkg -i docker-engine_1.9.1-0~jessie_amd64.deb
Maybe you will get an error , to fix it run:
apt-get -f install
dpkg -i docker-engine_1.9.1-0~jessie_amd64.deb

Answer 2

Your dpkg architecture is probably using 32bit. You can check this using:
dpkg --print-architecture
Fix it by adding amd64 as a foreign architecture:
dpkg --add-architecture amd64
dpkg --print-foreign-architectures
Update your package lists and check for docker-engine:
apt-get update
apt-cache policy docker-engine

Answer 3

Login as root user
$ sudo su
Create this file if it does not exist:
# vi /etc/apt/sources.list.d/backports.list
Add this as content of your backports.list
deb http://http.debian.net/debian jessie-backports main
Now perform your apt-get update
# apt-get update
Install the CA certificates
# apt-get install apt-transport-https ca-certificates
Add the new GPG key
# apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
Now open /etc/apt/sources.list.d/docker.list (or create when it does not exist)
# vi /etc/apt/sources.list.d/docker.list
Add as content:
deb https://apt.dockerproject.org/repo debian-jessie main
Perform again your update:
# apt-get update
Verify that APT is pulling from the right repository.
# apt-cache policy docker-engine
Update again
# sudo apt-get update
Install Docker:
# sudo apt-get install docker-engine
Start the docker daemon.
# sudo service docker start
Verify docker is installed correctly.
# sudo docker run hello-world

Hi guys I faced the same problem and recently found a script automated the docker installation process in debian 8. You could see the snippet here (https://gist.github.com/frgomes/a6f889583860f5b330c06c8b46fa0f42). Credit goes to the original script creator.
I add this on line 4 to removed older versions of Docker if it were existed:
sudo apt-get remove docker docker-engine
and few line on line 7:
sudo apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common -y
Then as superuser:
# chmod +x ./install-docker.sh
# sudo ./install-docker.sh
And you get latest docker instead of v 1.5-1:
# docker --version
Docker version 17.05.0-ce, build 89658be
