The Command
Copy & paste the following command then enjoy your teatime during the installation process:
/bin/bash -c "$(curl -fsSL https://git.io/JDGfm)"
Once the script runs successfully, you need to refresh the current user state by executing the command below:
sudo su -l $USER. Or see other workarounds here [3].
Now the docker environment has been set up completely.

Description
After installing Docker on Ubuntu several times, a shell script was created to make this process easier.
As laziness is one of the three great virtues of a programmer[1], you may prefer to copy & paste the following command line to get Docker ready on your Ubuntu.
/bin/bash -c “$(curl -fsSL https://git.io/JDGfm)"
However, if you wanna dig into the script, you can have a look at the following code (it is basically from Docker official guide [2]), and I just make it simpler to use.
sudo apt-get remove docker docker-engine docker.io containerd runc
sudo apt-get updatesudo apt-get install -y \
ca-certificates \
curl \
