Installing Docker on Linux Mint 20.x / Ubuntu (Jammy 22.04 / Impish 21.10 / Focal 20.04 / Bionic 18.04)

Uninstall old versions

sudo apt-get remove docker docker-engine docker.io containerd runc

If apt-get reports that none of these packages are installed, that means we havn’t installed Docker previously.

Installation

I prefer setting up Docker’s repository and install from that source for ease of installation and upgrade.

Set up the repository

1. Update the apt package index

    sudo apt-get update
   

2. Install required packages

    sudo apt-get install ca-certificates curl gnupg lsb-release
   

3. Add Docker’s official GPG key

    sudo mkdir -p /etc/apt/keyrings
    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
   

4. Set up the repository

Linux Mint 20.x

The Linux Mint 20.x is based on Ubuntu focal & we have to use it as source.

echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu focal stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Ubuntu - Jammy 22.04 / Impish 21.10 / Focal 20.04 / Bionic 18.04

echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Install Docker Engine

1. Update the apt package index

    sudo apt-get update
   

2. Install the latest version of Docker Engine, containerd, and Docker Compose.

    sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
