Ubuntu – Emacs info manual missing in Ubuntu 17.10

17.10debiandocumentationemacspackage-management

On Ubuntu 17.10, installing Emacs via $sudo apt install emacs
and then trying to view the Emacs manual using C-h r fails with error "Info file emacs does not exist" The same set of instructions on Ubuntu 16.04 works and one ends up with a local copy of the GNU emacs manual. Did the documentation get delegated to another package or is missing on purpose?
Thanks

The Emacs documentation is in the package emacs25-common-non-dfsg.
