Mongo DB Installation (Ubuntu)

Mongo Server [Not using this one]

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
sudo apt-get update
sudo apt-get install -y mongodb-org=3.2.6 mongodb-org-server=3.2.6 mongodb-org-shell=3.2.6 mongodb-org-mongos=3.2.6 mongodb-org-tools=3.2.6
echo "MongoDB v3.2.6 installed successfully"

Above didn't work for me. [Not using this one] But the below instead:
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/ This also not working

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
sudo apt-get update
sudo apt-get install -y mongodb-org

sudo service mongodb start
mongo
db.version()

WORKING SOLUTION

sudo rm /etc/apt/sources.list.d/mongodb*.list
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv E52529D4
sudo bash -c 'echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.0 multiverse" > /etc/apt/sources.list.d/mongodb-org-4.0.list'

sudo apt update
sudo apt install mongodb-org


# Enable the mongod service and start it up:
systemctl enable mongod.service
systemctl start mongod.service


# Check version
mongo --version

# Check the status
systemctl status mongod.service

In LOCALHOST, this one worked for me :) (But this will install 2.6.x version) [Not using this one]

sudo apt-get install --reinstall mongodb

Start & check

sudo service mongod start
netstat -tulpn | grep 27017
mongo
> db.version()

Mongo PHP Extension

sudo apt-get install php-pear
sudo pecl install mongodb

#sudo echo "extension=mongodb.so" >> `php --ini | grep "Loaded Configuration" | sed -e "s|.*:\s*||"`
sudo bash -c 'echo "extension=mongodb.so" > /etc/php/7.0/mods-available/mongodb.ini'
sudo ln -s /etc/php/7.0/mods-available/mongodb.ini /etc/php/7.0/cli/conf.d/30-mongodb.ini
sudo service php7.0-fpm restart
php -m | grep mongo

# phpize for PHP7 is provided by the package php7.0-dev in Ubuntu 16.04
sudo apt-get install php7.0-dev  

Problem

Failed to start mongodb.service: Unit mongodb.service is masked. Solution:

sudo systemctl unmask mongodb

Problem

If you are getting undesired Mongodb version, make sure you have only one source list under: /etc/apt/sources.list.d/

apt-get autoremove --purge mongodb-org*

Problem
