I have followed official instructions for Docker installation - Debian Jessie.

• In /etc/apt/sources.list it says now,

  deb [arch=amd64] jessie stable

• apt-get update seems to download packages correctly (output below)

• but then, on apt-get install docker-ce, the system reports to be "unable to locate package docker-ce".

How can I debug what is happening? Never had this before.

Output of apt-get update:

To install docker-ce on debian jessie:

After adding deb [arch=amd64] jessie stable to your /etc/sources.list. ( you don't need the software-properties-common package or the add-apt-repository command)

Install the required package:

sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl

Add the gpg key:

curl -fsSl | sudo apt-get key add -

Update and search for docker-ce package:

sudo apt-get update
apt-cache search docker-ce

Then install the docker-ce package:

sudo apt-get install docker-ce
