This seemed unobjectionable so I pushed the change here (https://hg.savannah.gnu.org/hgweb/octave/rev/182a8207a313).  Marking as fixed and closing report.

@Mike: This bug is ancient, but the patch still seems relevant.  and simple.  Can you verify if it could be applied since it concerns packaging?

Yes, thank you, I've been meaning to look into this. This error has affected a lot of Ubuntu users who have installed Octave in /usr/local for example, and then install the deb package which runs pkg rebuild -global and fails.

In the absence of any octave forge packages, /usr/share/octave/packages does not exist (maybe because it is empty it is not created by makepkg or pacman). In this situation, the following command fails:

> pkg rebuild -global

error: couldn't read directory /usr/share/octave/packages: No such file or directory
error: called from
rebuild at line 29 column 7
pkg at line 505 column 25

I use pkg rebuild to update the package database after installing or removing packages. When all octave forge packages are removed, this error appears for the last package, since at that point /usr/share/octave/packages will also be removed. It is not possible to update the package database unless one manually re-creates /usr/share/octave/packages.

A similar bug was reported and fixed in octave here:
bug #36830: Create pkg prefix directory, if it does not exist

I am attaching a patch which checks that the directory exists and if not, it will update the package database to an empty list (as appropriate). The patch applies to Octave 4.0.0.
