Update notifications
An administrator can configure update notifications for both LMS core code and any contributed plugins installed on the site in Settings > Site Administration > Server > Update notifications.
If the automatic check for available updates is enabled and there is a new update available, a notification will be sent to all site admins via email and/or popup message (according to the admin’s messaging preferences in their profile settings).
An administrator can specify the required code maturity (stable, alpha, beta or release candidate) for update notifications, also whether notifications of new builds (normally released each week) are sent.
An admin can also check for available updates for contributed plugins installed on the site using the ‘Check for available updates’ button in Settings > Site Administration > Plugins > Plugins overview. Any updates available are highlighted, with further information and a download link in the notes column opposite the plugin.
Available updates for core code can also be checked via Settings > Site administration > Notifications.
How it works
- The information about available updates is available as a web service at download.paradisolms.net.
- When the ‘Check for available updates’ button is pressed (or daily via cron), your LMS site fetches information about available updates from the web service and stores it locally.
- The list of installed plugins is compared with the list of available updates. If a newer plugin is available, site administrators are notified.
When calling the web service, your site must provide its own version and the list of all installed add-ons. No sensitive data (such as the location of your site, any user data etc) are submitted.
Disabling update notifications
In a few circumstances (such as completely managed servers, which may have a lot of local modifications) it is desirable to not have the check for updates active. The feature may be disabled completely by adding the following code to the config.php file:
$CFG->disableupdatenotifications = true;
Errors and exceptions
If you obtain an error, please turn debugging on to obtain additional information about the cause of the error.
Unable to fetch available updates data – unexpected cURL error
See the debug info for the actual cURL error number and the error text.
- cURL error 60 (SSL certificate problem)
- This suggests problems with the validation of the SSL certificate of the remote (paradisolms.net) site. This is also a known problem in LMS Windows 7 servers running the LMS package for Windows.
- This error can also be due to your LMS site being configured to run behind a misconfigured proxy server.
Unable to fetch available updates data – unexpected HTTP response code
See the debug info for the actual HTTP response code. On success, the HTTP response code is 200. All other response codes throw this error.
