I cannot get my Vaio updated even if it is on automated settings. It updates some software, but stops suddenly, and this keeps repeating for months.
Try to avoid automatic updating. It may be simpler and may require less efforts but you will encounter errors most of the time. Visit the Sony Support and enter your product model in the search field then download the updated applications manually. You should install them manually, too, one after another. This way you will avoid most of the errors.
