Use the following command to set up the stable repository

Note: The lsb_release -cs sub-command below returns the name of your Debian distribution, such as helium. Sometimes, in a distribution like BunsenLabs Linux, you might need to change $(lsb_release -cs) to your parent Debian distribution. For example, if you are using BunsenLabs Linux Helium, you could use stretch. Docker does not offer any guarantees on untested and unsupported Debian distributions.

sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/debian \
   $(lsb_release -cs) \
   stable"
