docker install failing on Ubuntu 14.04 with docker-ce-rootless-extras package not found

[parepallykiran]

Running below command on Ubuntu 14.04 is failing with mentioned error:

Command:
curl -sSL https://get.docker.com/ | sh

Error:
sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -qq docker-ce-rootless-extras >/dev/null
E: Unable to locate package docker-ce-rootless-extras

We don't see required package is available for Ubuntu v14.04. Its available only from Ubuntu 20.x. https://download.docker.com/linux/ubuntu/dists/trusty/pool/stable/amd64/

We are using Vagrant docker provisioner and vagrant is running above mentioned command to install docker on VM. This worked without any issues in the past.

I could observe the same problem here with Debian 9 (stretch)

Ubuntu 14.04 and Debian 9 reached EOL, so they are no longer supported

Could it skip the installation for docker-ce-rootless-extras on Ubuntu 14.04?

[thaJeztah]

The convenience script at get.docker.com is to install the latest version of docker; given that 14.04 and debian 9 reached EOL, and we no longe update those packages, we won't update the script for things we no longer ship.

I highly recommend upgrading your systems as they're no longer receiving updates (including security fixes); and older version of docker contain unpatched vulnerabilities (some of which may be critical).

If you really need to install on older platforms for some reason; either

• copy the install script and update it for your situation
• download an older version of the script from github (probably the commit before install docker-ce-rootless-extras explicitly + unrecommend sudo usermod -aG docker me #215)
• follow the manual installation procedure from https://docs.docker.com/engine/install/ubuntu/ or https://docs.docker.com/engine/install/debian/

I'm closing this ticket because of the above, but feel free to continue the conversation
