Disable all plugins manually (do not enable safe mode) and try to update the UPM.
Cause
There is a plugin that is causing conflict that, in turn, causes the install to hang.
Solution
Workaround
Disable all plugins and run the UPM.
Resolution
To find the offending plugin, please use the following steps after you have confirmed the update works when disabling plugins.
Stop the Confluence service
Run this query on your database:
1select plugindataid,pluginkey,filename,lastmoddate from plugindata;Please make note of what plugindataid is associated with the com.atlassian.upm.atlassian-universal-plugin-manager-plugin
Then run:
1delete from plugindata where plugindataid = <pluginid from upm>;changing <pluginid from upm> to the number you found in step 3
Delete 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
With all of the plugins disabled, re-enable each plugin one-at-a-time and try to update the UPM
Once the offending plugin is found, either remove or update the plugin
