When a program in Ubuntu such as crontab -e or dch -i, is used to edit a file, it uses a helper program called sensible-editor.
sensible-editor attempts to intelligently find an editor on your system based on a few simple rules. Basically, if you haven’t already defined $EDITOR, it will use one of {nano, nano-tiny, vi}, in that order.
Now, it’s well understood that nano is easier to use than vi to a new Ubuntu user. And it’s assumed that if you are sophisticated enough to want a different editor, then you likely already know how to change that setting.
