Big Sur update

I just purchased my Mac mini on Saturday. It will not update the big sur 11.1 and keeps saying 'some updates could not be installed'. When I click details it simply gives me the screen to update now or later, I click now, and it asks for my password, type it in, and hit update, and it tells me the same message...it's a vicious circle.
I'm getting the same thing on my MacMini M1, too - the upgrade went fine on my 2018 MacBook Air though.
Same problem on my MacBook Air M1. It came with 11.1 and won't update to 11.2.
