Docker 1.12 with Ubuntu 17.10 (Artful)

Hello everyone,

I have a question related to Docker and Ubuntu 17.10.
Actually I have Docker 17.11.0-ce, build 1caf76c.

I use a script, which, unfortunately works only with docker 1.12.6 (it worked fine under Ubuntu 16.04).

So I checked https://docs.docker.com/cs-engine/1.12/ and tried
apt-get install docker-engine=1.12.6
but Version ‘1.12.6’ for ‘docker-engine’ was not found.

I guess there is no possibility to install docker 1.12.6 on Ubuntu Artful isn’t it?

Many thanks for your help !
