Installing MongoDB Community Server on Ubuntu 20.04 LTS

Ubuntu on Windows Subsystem for Linux cannot use this method because systemd is not enabled.

1. Import MongoDB GnuPG public key
   wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
2. Insert a repository entry in APT source list
   echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
3. Update apt package list
   sudo apt-get update
4. Install MongoDB server by issuing command:
   sudo apt-get install -y mongodb-org
5. Run MongoDB server as a service
   sudo systemctl start mongod
6. Verify that MongoDB server is installed and running:
   sudo systemctl status mongod

Sample output if the service is running:
