Mac OS cant install update - "Mac OS Big Sur could not be verified"

Tried to update my mac book air several times but always failed.  Turns out the problem was macOS Catalina had some other updates it needed to install.  After I installed those updates I was able to upgrade to Big Sur no problem.

In the system update window there was another link for "other updates" or something like that.  This is where I installed the macOS Catalina updates.
