When I tried to upload new version of our plugin for the Moodle 3.8, the following error was displayed.

Errors parsing db/install.xml: PATH attribute does not match file directory: /var/www/temp/local_plugins/version_upload/387026789/kalmediaassign/db

Our plugin name is "mod_kalmediaassign", and "install.xml" is placed in "mod/kalmediaassign/db" directory.

I describe the XML header of "install.xml" as follows:

<?xml version="1.0" encoding="UTF-8" ?>
<XMLDB PATH="mod/kalmediaassign/db" VERSION="2019111400" COMMENT="XMLDB file for Moodle mod/kalmediaassign"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="../../../lib/xmldb/xmldb.xsd"
>

I seem that our "install.xml" has no issue.

But, I cannot upload this plugin.
