While performing an upgrade of an existing ScaleArc system, the 'Apply' button is disabled. Such a situation may occur when a user is uploading the same version of installed software more than once.
As a workaround follow the steps below:
1. Check if /tmp/upgrade_status file is present then delete it.
2. Create a file /opt/idb/package/idbpkg/package_name
3. Put Installer file name in /opt/idb/package/idbpkg/package_name
4. Refresh the 'System Settings' page. The 'Apply' button should be enabled.
