Your older and newer reports:

expected 0/0 versus actual 1001/100
vs.
expected 0/0 versus actual 1001/0

Looking for the code in pkg finds it in pkgdb.c :

	if (wrong_owner) {
		pkg_emit_error("%s wrong user or group ownership"
			       " (expected %d/%d versus actual %d/%d)",
			       path, fileowner, filegroup, sb.st_uid, sb.st_gid);
		return (EPKG_INSECURE);
	}

So: the group id changed to 0 but the user id did not:
still 1001 on the directory or file being checked.

But our reports both say: . wrong user or group ownership,
so here it is the (potential) containing directory: ".".

I'm not making claims about what lead to sb.st_gid==0 for
"." , just noting that it did change to that.

Looking around the code seems to be used for
local.sqlite or its containing directory, here the
directory.

Might this be related to the "NO_ROOT=YES" usage that
you originally reported?
