• Download URLs need to be re-configured.

3. Select Custom Repository: Choose the option to Use Specified Repository. 
4. Enter the URL: Provide the URL of your custom local web server repository. And Save Changes and Check for Updates: Click Save, then click Check Updates to verify the new configuration:
