To uninstall MongoDB from Ubuntu, first stop the Mongo Daemon if it is already running, remove MongoDB packages using APT (Advanced Package Tool), and finally remove the MongoDB logs from log directory, and MongoDB Databases from library.
Following are the list of commands that have to executed in order to uninstall MongoDB from Ubuntu.

Following is a detailed step by step process to uninstall MongoDB. Open a Terminal and follow these steps one by one sequentially.
1. Stop Mongo Daemon
We have to stop Mongo Daemon if it is already running in the system.
Run the following command in a Terminal.
sudo service mongod stop
Stopping Mongo Daemon ensures that there are no locks on any database files or such.
2. Remove MongoDB Packages
Now, we have to remove MongoDB packages. We will use apt command to purge MongoDB packages.
Running the following command removes all the installed packages for MongoDB.
sudo apt-get purge mongodb-org*
3. Remove MongoDB Logs
Any logs for MongoDB, by default, is written to the location /var/log/mongodb/. Remove /var/log/mongodb/ and its sub-directories recursively.
sudo rm -r /var/log/mongodb
4. Remove MongoDB Databases
Any databases created in MongoDB, by default, is written to the location /var/lib/mongodb/. Remove /var/lib/mongodb/ and its sub-directories recursively.
sudo rm -r /var/lib/mongodb
If you have created any other directories for MongoDB databases, you may also remove them.
