How to Enable Official MongoDB Repository?

We need to first identify the latest version of the MongoDB package to import Official GPG key of MongoDB repository before installing MongoDB.

Checkout this site to get the latest MongoDB Server version : https://pgp.mongodb.com/

At the time of creating this post, it was 5.0. So will use 5.0 as the MongoDB version throughout this tutorial post.

Use "curl" and "apt-key" together to import MongoDB GPG key.

congo@ubuntu:~$ sudo curl -fsSL https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -

Once GPG key is added, we can enable the MongoDB official repository as below. Make sure to change the latest version you have got from their site.

congo@ubuntu:~$ sudo echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu $(lsb_release -cs)/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb.list
