How to update the version of MongoDB on your machine on different platforms and versions.
If you have an older version of MongoDB, you must upgrade the whole path to the newest version. For example, if you are running version 3.0 and want to get version 3.4, you must upgrade 3.0->3.2->3.4.
You must have 3.2 to be able to upgrade to 3.4. This example assumes you are using
sudo service mongod stop
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6
echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list
sudo apt-get update
sudo apt-get upgrade
sudo service mongod start
Ensure the new version is running with
mongo. The shell will print out the MongoDB server version that should be 3.4 now.
