Install Docker on Raspberry Pi 4 with Ubuntu 20.04

In the documentation of Docker it says to install the OS version with lsb_release -cs. For me this returned focal, but Docker does not have the release files for that version it seems.

I got errors like E: Package 'docker-ce' has no installation candidate.

Just change lsb_release -cs to bionic (for armhf):

sudo add-apt-repository \
   "deb [arch=armhf] \
   bionic \

I installed the 32 bit version so then you need armhf, but it might be different for you. Just check the command apt policy to see what your system is using. It returns something like ... Packages. Where ... is your type of installation.

After that you can just install Docker

sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli

Happy coding! – Found a mistake or a typo? Please submit a PR to my GitHub-repo.
