I tried to install MongoDB, but something went wrong with the installation and I want to install it again. Unfortunately, I get errors when attempting to remove/pruge, and I suspect those errors might be related to my subsequent failures to reinstall.

I am confused is it already fully removed and that's why I am getting these errors, or is it failing to remove? If so, then how is dpkg coming up with the number 62.2 Mb to be removed? Would I be better of nuking my entire Ubuntu installation and starting fromm scratch? Is there a good, COMPLETE guide to installing MongoDB on Ubuntu 18.04? Because even to get my previous broken install partly looking, I had to do stuff suggested in threads that was not mentioned in the official install guide.

Edit: to be clear the issue is that I CANNOT apt-get purge mongo, and the service isn't even running.

It turns out that there were some mongdb related files hanging around in /var/lib/dpkg/info that, once deleted, allowed purge to complete successfully.
I am pretty mad at the mongoDB documentation for advising that their package was better maintained than the OS repositories and that I should install from their repository.
