Thanks for this. However neither man-db, xdg-utils not manpages-dev are forked
packages in Devuan and we use Debian's packages directly without recompilation.

Please report this issue to Debian's BTS.

Thanks.

Got a "wontfix" and "bug closed" from Debian:

"Yes, that's because /usr/share/man/man1/open.1.gz exists as an
alternative which is symlinked to xdg-open.1.gz on your system (via
alternatives), and section 1 is first in the priority list, so man is
working as designed.  Use "man 2 open" to get the page for the system
call."

What nutball does such things?

Nik

The command is working as intended.

When manpages in multiple sections of the manual share the same name,
the page from the earliest section of the manual is fetched and
displayed in response to running 'man <manpage>'.

The xdg-utils package includes an alias for /usr/bin/xdg-open in the
form of /usr/bin/open. A manpage alias is included in the same fashion,
thus both sections 1 and 2 of the manual have a manpage for 'open'.

To specify from which section of the manual to display a manpage,
proceed the name of the manpage with the section number,
i.e.'man 2 open'. To display matching manpages from all sections, use
the -a option, i.e. 'man -a open'.

So what would you suggest? File a bugrport for "xdg-utils"?

You could try.

The Ubuntu bug is also worth reading[2], but might not give you much
encouragement.

Whilst it is only a workaround, you might be able to fix the behaviour with (untested)

  update-alternatives --remove open /usr/bin/open
