[Bug 1548477] Re: man seems to be using primitive 'more' rather than 'less'

[sudodus]

This is during testing the Lubuntu Xenial desktop iso file.

Yes less is installed, and can be used to display text files. But man
falls back to more. If man-db is not changed, something else has changed
during the last few days, because I have checked

man usb-creator-gtk

a few times recently to check if the version number has been updated, and this is the first time this bug occurs.

Title:
  man seems to be using primitive 'more' rather than 'less'

Status in man-db package in Ubuntu:
  Incomplete

Bug description:
  When reading a manual page with man, I can only step lines forward
  with Enter or step pages with space. I suspect that 'more' is used
  instead of 'less', which makes it much harder to navigate in the
  manual documents. I think this bug has appeared recently (after alpha
  2).

  The last page of man man looks like this:
