Summary
The "Upload app" option under the Manage Apps menu isn't visible after upgrading to Confluence Data Center 7.19.20 or 8.5.7 and above.
Enable the ability to upload apps
For higher security, the option to upload an app from the Confluence UI (Upload app link) is disabled by default on the latest versions of Confluence Data Center. This is one of the changes in how Atlassian Data Center products, including Confluence, handle app installations through the Universal Plugin Manager (UPM) and REST APIs.
The Confluence administrator can re-enable the UI upload button and API by following the below:
Note that these steps need to be carried out in every node of your Confluence instance.
- Stop Confluence
Configure System Properties, by adding "-Dupm.plugin.upload.enabled=true" to the the Confluence settings.
CATALINA_OPTS="-Dupm.plugin.upload.enabled=true ${CATALINA_OPTS}"- Restart Confluence
When set to true, this property enables API app installation. Setting it to true will require a restart.
For higher security, leave this set to false when no apps need to be installed.
Environment
Confluence 7.19.20 or higher
Confluence 8.5.7 or higher
