[UPDATED 05 Aug 2019] It is now possible to run Ubuntu 18.04.2 (ARM 64-bit) directly on the Raspberry Pi 3 (not yet on 4). You can read more about this and get SD Card images from the Ubuntu wiki. I am using the server version of “Ubuntu Classic” as opposed to the new “Snappy Ubuntu Core.” MongoDB has an official release of MongoDB
4.0.6 4.0.11 for “Ubuntu 16.04 Linux 64-bit ARM 64.” I will show how to install this version of MongoDB under Ubuntu 18.04 on the Raspberry Pi 3B+. These instructions should work for any version of R-Pi 3 but I have only tested on my Raspberry Pi 3B+.
Download the ARM64 image for the Raspberry Pi 3 as instructed on the Ubuntu Wiki. The download link as of August 2019 is Ubuntu Server image for Raspberry Pi 3 (440MB compressed). This is an R-Pi image that needs to be written to the Micro SD Card – as usual. It is important to read the install directions on the wiki!
Note that you might see key-exchanges going on at first boot. The file system also auto-expands – so give it some time for first boot. The login/password is ubuntu/ubuntu. You will be prompted to change. “raspi-config” does NOT work! I am using the ethernet connection so no network configuration is required. WiFi is supported under Ubuntu Server 18.04 but is not the easiest to setup — and is beyond the scope of this post — read the docs 😉
After a successful boot, make sure your OS is up to date:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
Here are my versions of name, kernel & OS info:

OK, let’s install the MongoDB Community Server and utilities.
Import the public key for the Package Management System:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4
Recent MongoDB docs (August 2019) say to use this method to get key, though either way should work:
wget -qO - https://www.mongodb.org/static/pgp/server-4.0.asc | sudo apt-key add -
Add a MongoDB list file from the “xenial” branch as MongoDB 4 is not yet in the “bionic” branch. Update the packages list. Install any updates and then install MongoDB. Note that “lincurl4” replaced “libcurl3” in Ubuntu 18.04. We need to revert to “libcurl3” for MongoDB 4.0 to install correctly. A simple “apt-get install” will do the trick.
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libcurl3
sudo apt-get install -y mongodb-org

Before running MongoDB, I add 2GB system swap space. This can slow things down considerably but I have, on occasion, had issues with some utilities such as “mongoimport” if I did not add space. Most of the time, swap space is not used and doesn’t impose a performance penalty. You could try running MongoDB (mongod, mongo) without swap but be aware of this swap option if things seem to hang.
sudo dd if=/dev/zero of=/swapfile.img bs=1M count=2048
sudo mkswap /swapfile.img
sudo swapon /swapfile.img
You can start MongoDB and check its status:
sudo service mongod start
sudo service mongod status
Run the MongoDB shell:
