What to do in this situation? Below are some steps you can take to troubleshoot this issue:

Check your Internet Connection

Make sure your device is properly connected to the Internet and that there are no problems with your internet connection. Sometimes the Hash Sum mismatch problem can occur due to an unreliable connection.

Update Repositories
