Which package contains /usr/bin/less for Ubuntu 19.04?

As in the title. Neither dpkg -S /usr/bin/less nor apt-file search /usr/bin/less produces anything useful.

Does it mean that there’s a bug or that less really doesn’t come from any package?

(In case you’re wondering why I need to know the answer, I find that the less is an old version 487 instead of 530 that has a feature I want.)
