Macos 14 Sonoma install problem

I am trying to upgrade to Sonoma; it shows in System Settings Software update and when I click on "upgrade" it downloads the install program and "installs" it but when computer reboots it still has older version. (System settings still shows upgrade available).

Is there a way to figure out why the install failed?

When I repeatd the exact same process this afternoon (Saturday June 10) the Sonoma beta installed successfully.
