Docker on Linux Mint 19

When attempting to install docker in Linux Mint 19 I had the following issue with the repository: The repository 'https://download.docker.com/linux/debian tara Release' does not have a Release file. So the issue was caused by the "lsb_release -cs" command that returns "tara" (the name of the linux mint release). It came out that I need to use the version of the Ubuntu origin: sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(. /etc/os-release; echo "$UBUNTU_CODENAME") stable" P.S. I had to delete the original entry that was suggested by the official docker manual: egrep -r docker /etc/apt/sources.list.d/
