In "Install MongoDB"

[j-i-m-s-t-e-r]

Get error below running "sudo apt-get install -y mongodb-org" :

"Reading package lists... Done Building dependency tree Reading state information...

WARNING: The following packages cannot be authenticated! mongodb-org-shell mongodb-org-server mongodb-org-mongos mongodb-org-tools mongodb-org E: There were unauthenticated packages and -y was used without --allow-unauthenticated

I guess "--allow-unauthenticated" will work but at users own risk.

the details for Mongodb are out of date and need to be updated (someone has already made a pull request)

1. wget -qO - https://www.mongodb.org/static/pgp/server-3.2.asc | sudo apt-key add -
2. echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
3. sudo apt-get update
4. sudo apt-get install -y mongodb-org
