Here’s a site i used when upgrading- everything went smoothly

Thanks, but I don’t need help upgrading to 19.x. I’m already there. I’d just like to move up to 19.3, although I’ve heard that version is experiencing some growing pains.
Really, all I’m trying to do is to get Linux to stop freezing. It works fine, otherwise.
