The minimal change is probably moving update-alternatives --quiet --remove pager /bin/less
from postinst to preinst. The pager alternative will fallback to 'more' at least until the new alternative is set up. Strictly speaking it is probably the most correct thing to do, as 'pager' is never left wrongly configured. However there are several packages calling `update-alternatives --install` from preinst [1]. That's probably OK too.
