Passcode is Not Set on macOS Sonoma and macOS Ventura

My iMac tells me there's an update to Ventura 13.0.1. But it won't do the update. Instead when I click on the link I get the following: "Passcode is not set. An error occurred while installing the selected updates." It also says my Mac will try this evening and automatically restart. It's been telling me this for several days, but does not do it. When I look online for info on Passcodes, all I get are references to iPhone and iPads. Can anyone gives me a way out of this troublesome notification? Thanks in advance.
