What about aarch64?
The repository at piwheels.org does not currently support the 64-bit version of the Raspberry Pi OS (currently in beta). We have plans to support it in future, but this requires a significant amount of work, and then rebuilding all wheels on the new architecture. Read more on the blog and issue #220.

Docker Installation

Install Docker Engine on Debian
Set up the repository


Update the apt package index and install packages to allow apt to use a repository over HTTPS:
$ sudo apt-get update

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


Add Docker’s official GPG key:
$ curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg


Use the following command to set up the stable repository. To add the nightly or test repository, add the word nightly or test (or both) after the word stable in the commands below. Learn about nightly and test channels.
$ echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null


Install Docker Engine

This procedure works for Debian on x86_64 / amd64, armhf, arm64, and Raspbian.


Update the apt package index, and install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:
 $ sudo apt-get update
 $ sudo apt-get install docker-ce docker-ce-cli containerd.io


Got multiple Docker repositories?
If you have multiple Docker repositories enabled, installing or updating without specifying a version in the apt-get install or apt-get update command always installs the highest possible version, which may not be appropriate for your stability needs.


To install a specific version of Docker Engine, list the available versions in the repo, then select and install:
a. List the versions available in your repo:
$ apt-cache madison docker-ce

  docker-ce | 5:18.09.1~3-0~debian-stretch | https://download.docker.com/linux/debian stretch/stable amd64 Packages
  docker-ce | 5:18.09.0~3-0~debian-stretch | https://download.docker.com/linux/debian stretch/stable amd64 Packages
  docker-ce | 18.06.1~ce~3-0~debian        | https://download.docker.com/linux/debian stretch/stable amd64 Packages
  docker-ce | 18.06.0~ce~3-0~debian        | https://download.docker.com/linux/debian stretch/stable amd64 Packages
b. Install a specific version using the version string from the second column, for example, 5:18.09.1~3-0~debian-stretch .
$ sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io


Verify that Docker Engine is installed correctly by running the hello-world image.
$ sudo docker run hello-world

This command downloads a test image and runs it in a container. When the container runs, it prints a message and exits.


Docker Engine is installed and running. The docker group is created but no users are added to it. You need to use sudo to run Docker commands. Continue to Linux postinstall to allow non-privileged users to run Docker commands and for other optional configuration steps.
Upgrade Docker Engine

To upgrade Docker Engine, first run sudo apt-get update, then follow the installation instructions, choosing the new version you want to install.
Add current user to docker group

$ sudo gpasswd -a $USER docker

$ newgrp docker

Installing snap on Raspberry Pi OS

Enter the following into the terminal:
$ sudo apt update
$ sudo apt install snapd
You will also need to reboot your device. This can be accomplished from the terminal (and from the desktop), but make sure you save any open documents first:
$ sudo reboot
After this, install the core snap in order to get the latest snapd.
$ sudo snap install core
core 16-2.45.2 from Canonical✓ installed
And then make snap zsh aware.
I can't use snap packages, even if installed
Modify oh-my-zsh profile
$ nano ~/.zshrc
Add this below,
# Make snapd zsh aware
emulate sh -c "source /etc/profile"

Morikko commented on Jan 31
I followed the answer here: https://stackoverflow.com/a/50958615/7186064I just commented the line. Now, I have no more messages and nextcloud works.
$ sudo nano /etc/ld.so.preload

Install Python on Raspberry Pi

sh-python-installer
Command '('lsb_release', '-a')' returned non-zero exit status 1

https://stackoverflow.com/a/66474609/9728243
I had this same problem with python 3.6 and python 3.7 on Raspberry Pi, but I thing it shall work anywhere.
The only thing that works like a charm was to move the lsb_release to a backup file.
 sudo mv /usr/bin/lsb_release /usr/bin/lsb_release_back
The complete doc can be found here: [readthedocs.io].[1]https://neoctobers.readthedocs.io/en/latest/rpi/install_python3.html
Check link

$ ls -l /usr/bin | grep python
Modify link

# ln -snf TARGET LINK_NAME
$ sudo ln -snf /usr/bin/python3.7 /usr/bin/python3
