I am currently conducting tests on moodle 2.4 (soon to be released) and have come upon a problem when trying to upgrade my current HP mod to your latest release.
When I visit admin->notifications, I am told that a new version of HP is available.
If I click the Download link I can download the zipped HP on my machine, and then unzip and copy to my moodle/mod folder, i.e. perform a "manual" install as usual. And it works fine!
Anyway I decided to try out the - new to moodle 2.4 - "automatic update" and clicked the Install this update button. But that threw out an error:
Oops! It did it again
Moodle deployment utility had a trouble with your request. See the debugging information for more details.
exception 'unauthorized_access_exception' with message 'Unable to read the passphrase file.' in moodle\mdeploy.php:830
#0 M:\server\htdocs\moodle24\moodle\mdeploy.php(699): worker->authorize()
#1 M:\server\htdocs\moodle24\moodle\mdeploy.php(1314): worker->execute()
Should I (or would you, Gordon) open an issue in the tracker?
