[docker install] does not work in Ubuntu 12.04

I've followed already this

~~[https://www.linode.com/docs/applications/containers/docker" target="_blank">](https://www.linode.com/docs/application … ers/docker">https://www.linode.com/docs/applications/containers/docker](

~~[https://docs.docker.com/installation/ubuntulinux/#ubuntu-precise-1204-lts-64-bit" target="_blank">](https://docs.docker.com/installation/ub … lts-64-bit">https://docs.docker.com/installation/ubuntulinux/#ubuntu-precise-1204-lts-64-bit](

but I'm still struggling to install it. For some weird reason it does not seem to find the installer. I've tried alternative mirrors like http://mirror.yandex.ru/mirrors/docker/ but I get exactly the same result regardless of the mirror.

root@development:~# cat /etc/apt/sources.list.d/docker.list

deb https://get.docker.com/ubuntu docker main

Has anybody successfully installed docker? I'm running on 3.18.5-x86_64-linode52 kernel and Ubuntu 12.04.5 LTS (precise)
