Understanding the Causes of Error -20
Before diving into the solutions, it’s helpful to understand what might be causing Error -20. Common reasons include:

Identifying the root cause can help you choose the most effective troubleshooting step. Now, let’s explore how to fix this error.
1. Check and Free Up Device Storage
One of the most common causes of installation errors is insufficient storage space. Follow these steps to check and free up space:
- Check Storage: Go to Settings > General > iPhone Storage to see available space.
- Delete Unnecessary Apps or Data: Remove apps, photos, videos, or files you no longer need.
- Clear App Cache: Some apps allow you to clear cache within their settings, freeing up space.
- Offload Unused Apps: Use the Offload Unused Apps feature to remove apps but retain their data.
Ensuring at least a few hundred MBs of free space can significantly improve the chances of a successful app installation.
2. Restart Your Device and Retry
A simple restart can often resolve temporary glitches causing Error -20:
- Press and hold the power button until the “slide to power off” slider appears.
- Slide to turn off your device.
- After a few seconds, press and hold the power button again to turn it back on.
Once restarted, try installing or updating the app again. This can clear minor software issues that interfere with installations.
3. Update iOS to the Latest Version
Outdated software can cause compatibility issues and errors. To ensure your device runs smoothly:
- Navigate to Settings > General > Software Update.
- If an update is available, tap Download and Install.
- Follow on-screen instructions to complete the update.
After updating, attempt to install the app again. Keeping your iOS current ensures compatibility with the latest apps and features.
4. Sign Out and Sign Back Into Your Apple ID
Sometimes, issues with your Apple ID can cause installation errors. To troubleshoot:
- Go to Settings > [Your Name] (Apple ID).

- Ensuring your Wi-Fi connection is stable and strong.
This step often resolves network-related errors that cause installation failures.
