I installed docker on Debian 8 Jessie before, following this instruction:

apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
echo "deb https://apt.dockerproject.org/repo debian-jessie main" > /etc/apt/sources.list.d/docker.list
apt-get install -y apt-transport-https ca-certificates
apt-get update && sudo apt-get install -y docker-engine

But starting from 31.03.2020 the repositories in apt.dockerproject.org are deprecated and I can't install docker from there anymore.

How can I install docker on Debian 8 Jessie now, since I've failed to do it from download.docker.com?

The Debian 8 "Jessie" has been discontinued as of June 2018 and the LTS will end in June 2020. Despite there seems to be a Docker release for Jessie on https://download.docker.com/linux/debian/dists/jessie/ it's last updated back in Jun 2019. You should be upgrading your system to a supported Debian 9 Stretch (oldstable) or Debian 10 Buster (stable), and then follow the instructions on Install Docker Engine on Debian.

That said, it seems this release is signed with the same signing keys (the key 7EA0A9C3F273FCD8 is a subkey of Docker Release (CE deb) <docker@docker.com> with ID 8D81803C0EBFCD88), so you should be able to use the same instructions for using the unsupported version still available on the server:

  • thanks for answer. So is it impossible to install docker without the Debian 8 upgrade? – dice2011 Apr 26 '20 at 08:50
  • Which part of the "*you should be able to use the same instructions*" was unclear to you? It might not be impossible, but it's certainly not recommendable. – Esa Jokinen Apr 26 '20 at 09:03

If despite the warnings of Debian Jessie being discontinued you still want to install Docker on it, try:

apt-get update
apt-get install -y sudo curl
curl -fsSL https://get.docker.com -o get-docker.sh
sh get-docker.sh

  • No longer works. Prints `DEPRECATION WARNING: This Linux distribution (debian jessie) reached end-of-life and is no longer supported by this script. No updates or security fixes will be released for this distribution, and users are recommended to upgrade to a currently maintained version of debian.` when run. Install fails even after waiting a while. – CLSA Jun 20 '22 at 14:05
