"mongodb-org : Depends: mongodb-org-server but it is not going to be installed" when installing mongodb in Ubuntu 20.04

Question

I've committed the error of installing mongodb first by sudo apt install mongodb, removing it and then trying to install as the official documentation says so for Ubuntu 20.04 (Linux Mint), but now I can't install any other package because it gives me:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 mongodb-org : Depends: mongodb-org-server but it is not going to be installed
               Depends: mongodb-org-mongos but it is not going to be installed
 mongodb-org-tools : Depends: mongodb-database-tools but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Tried sudo apt reinstall sudo apt --fix-broken install sudo apt purge <package_name> sudo apt remove <package_name> sudo apt-get install -f

When running sudo apt install --fix-broken:

sudo apt install --fix-broken

The following additional packages will be installed:
  mongodb-database-tools mongodb-org-mongos mongodb-org-server
The following NEW packages will be installed:
  mongodb-database-tools mongodb-org-mongos mongodb-org-server

If I try to reinstall mongodb following the official doc it gives me again the same error I've mentioned before. Thanks in advance.

This solved my problem; dpkg -l | grep mongo will show the list of packages, then dpkg -r <nameofpkg> could be used for each packages for the output of dpkg -l | grep mongo.
