My guess is that you installed Certbot both from the Python Package 
repository and also from an Ubuntu package repository.

You should install a Python package one way or the other, not both. 
Otherwise you will get problems like this.

If you run:

dpkg -s python3-certbot

or similar (try 'dpkg --get-selections |grep certbot' if you can't find 
the package).

I would recommend removing the Ubuntu package if you are working with a 
package installed via pip.

BTW: randomly deleting directories is generally not a good idea, 
particularly if you have installed from a package.  All packages provide a 
method to remove it, even programs compiled from source will usually have 
the ability to "make uninstall".
