Summary
Sometimes you're unable to access the Add-Ons in the Confluence Administration page because the Universal Plugin Manager (UPM) is somehow corrupted.
Or, the default upgrade process for UPM doesn't work.
Solution
Try to clear the Plugin Cache first to see if it works.
Update all incompatible plugins to the compatible version and disable those that are totally incompatible.
If you're unable to update or if it still fails, try the steps below
Only perform the steps below as a last resort after ensuring that
The Server Base URL is correct and it's the same with the URL that you're accessing Confluence with
The proxy (if there is) and firewall have been configured correctly. Check your server.xml and if you have proxy or SSL, ensure the settings are there.
To manually reset the UPM :
We would need to delete some entry from the database.
Please backup your Confluence Home Directory, Installation Directory and your database before proceeding. This is very important because we're performing some database manipulation which might break Confluence if it's done incorrectly If possible, try this out on a cloned test instance first.
Go to Confluence Administration >> Manage Add-Ons and take note of your UPM version.
Shut down Confluence.
Run this SQL query on your Confluence database
1delete from plugindata where PLUGINKEY='com.atlassian.upm.atlassian-universal-plugin-manager-plugin'Go to
<Confluence Installation Directory>/confluence/WEB-INF/atlassian-bundled-pluginsand search for allatlassian-universal-plugin-manager-pluginand delete the JAR file. By default, it's only 1 JAR file.Then, clear the plugin cache again by deleting the following folders.
<confluence-home>/bundled-plugins
<confluence-home>/plugins-cache
<confluence-home>/plugins-osgi-cache
<confluence-home>/plugins-temp
<confluence-home>/bundled-plugins_language (This may, or may not exist)
Download the same UPM version in step 1 and ensure that it is compatible with your Confluence version.
Go to
<Confluence Installation Directory>/confluence/WEB-INF/atlassian-bundled-pluginsand copy this JAR file into the folder.Start up Confluence
To manually upgrade the UPM :
Try to update the UPM via file upload if the default method is not working. Ensure that the UPM version downloaded is compatible with your Confluence version
If it's not working, ensure that The Server Base URL is configured correctly.
Only if it's still not working, we would need to delete some entry from the database.

Download the UPM version that you wish to upgrade to and ensure that it is compatible with your Confluence version.
Place the newly downloaded UPM JAR into <Confluence Installation Directory>/confluence/WEB-INF/atlassian-bundled-plugins where the previous JAR file was deleted
Start up Confluence
