    Display user friendly error on medium analysis failures
    
    When trying to install from a corrupted ISO (for example a 0-byte)
    ISO, the error from libosinfo is displayed to the user, and these
    are not user friendly messages. Replace it with a user-friendly
    message, and only log the initial error to the console.
