I checked in the patch under Nicholas's name here (https://hg.savannah.gnu.org/hgweb/octave/rev/b964092ad9f8).  This will be a part of the Octave 5.0 release scheduled for January.

Thanks for the code, and sorry it took so long to get it applied.

I ran into the same problem, trying to update a specific package on octave 4.2.1. The changes specified here fixed the problem for me. I hope they can be integrated in to the next octave version.

Also had to tweak one of the following lines:

update_lst = { update_lst, installed_pkgs_lst{idx} };


update_lst = [ update_lst, installed_pkgs_lst(idx) ];

otherwise it would concatenate the empty cell, which would break the later .name call on line 548 since it still looked like a cell not a struct.

patch attached

first noticed using Octave 4.0.2, Windows 32bit, zip-file install. 

"pkg update pkgname1 _pkgname2_ ..." produced an error because of 'installed_pkgs_list' not being defined. Saw that the dev branch had a fix for this and a following line defining update_lst, but searching failed to find me a bug/patch tracker related to these fixes.  The dev version still gives the following error:

>> pkg update control signal
error: cell cannot be indexed with .

the line of interest is:

 installed_names = {installed_pkgs_lst.name}';

but installed_pkgs_lst is a cell array of structs, so .name errors out. the following line does work:

#installed_names = cellfun (@(idx) idx.name, installed_pkgs_lst, 'UniformOutput', false);

With this running the pkg command above works. Will upload a patch for review to implement this fix.
