Step 2: Install MongoDB On Ubuntu 20.04

As the Ubuntu Official repository doesn’t have the latest version of the MongoDB, so in order to install the latest version, we’ve to install it manually. Currently the latest stable releases of MongoDB is 4.4, so we’ll install it on our system. Simply follow the below steps for an easy and optimal installation.

Now, to import the GPG key hit the below command.

sabi@Ubuntu20:~$ wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
[sudo] password for sabi:
OK

You’ll get the “Ok” message as output if it is successfull. If you face any error retry adding the key or hit the below command to install gnupg (for gnupg error).

sudo apt-get install gnupg

Once it is installed, hit the following command to import the GPG key.

wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -

Step 3: Create A List File For MongoDB Package

Create the list file in the /etc/apt/sources.list.d/ directory for Ubuntu 20.04.

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

And then update the system again.

sudo apt update

Step 4: Install MongoDB
