Steps to reproduce the issue

• Setup live site from 5.4-dev with disabling automated updates after installation
• Install 'System - Alpha Update Server' plugin from #45540
• Enable Automated Updates
• Check administrator/logs/joomla_update.php file

Expected result

• Clear log messages with something like 'Attempting to download update file from ' to clarify the system is now trying to download
• In best case an success message e.g. 'Downloaded successfully'

Actual result

• There are four identical log messages, without any indication for success, which may leave questions unanswered for an administrator:
