Change to default python3 version on Raspberry Pi OS:
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1 sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.7 2 # check the list sudo update-alternatives --list python /usr/bin/python2.7 /usr/bin/python3.7 # Change the default version sudo update-alternatives --config python There are 2 choices for the alternative python (providing /usr/bin/python). Selection Path Priority Status ------------------------------------------------------------ * 0 /usr/bin/python3.7 2 auto mode 1 /usr/bin/python2.7 1 manual mode 2 /usr/bin/python3.7 2 manual mode Press <enter> to keep the current choice[*], or type selection number: # now Python 3 is default python Python 3.7.3 (default, Jul 25 2020, 13:03:44) [GCC 8.3.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>>

[64-bit Raspberry OS Buster]
We are going to use instructions for Ubuntu 64-bit:
ADDED OPTION -L to support re-direct… (May, 7, 2022)
curl -s -L https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add - echo "deb [ arch=arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list sudo apt update
Now we can install MongoDB server:
sudo apt install mongodb-org # enable and start sudo systemctl enable mongod sudo systemctl start mongod
sudo apt install php-dev sudo pecl install mongodb
…of course:
sudo apt update && sudo apt upgrade
Install docker:
Method 1:
sudo apt install docker.io
[1: Recommended] for 64-bit only. Raspberry OS 32-bit is already coming with Node-Red pre-installed
you will get:
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
To install/upgrade the Composer:
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" # php -r "if (hash_file('sha384', 'composer-setup.php') === '756890a4488ce9024fc62c56153228907f1545c228516cbf63f885e036d37e9a59d27d63f46af1d4d07ee0f76181c7d3') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
They “still recommend the 32 bit operating system for all Pis at this time, although have decided it is now time to begin the move toward a 64-bit OS. For the moment this is a ‘beta’ program, the OS is in heavy flux and its functionality is likely to change significantly over the next few months…”
Disadvantages:
Advantages:
The one thing I would recommend for now, do not follow the link to download image. Just go:
https://downloads.raspberrypi.org/raspios_arm64/images/
You should see more folders there, dig into the most recent, and download (click) .zip file with the image. Write the image on SD card, USB drive (using for ex: win32diskimager), put into the slot, since Sep 2020 Raspberry Pi 4 can boot directly from USB without SD card – and start the system. Just install OS on ANY (small, slow, etc.) card, change the settings running
raspi-config
… remove card, burn image on USB drive, and get everything installed on it.
