By ISO Up to and including 20236, the previous version could be updated. (ISO) Since this version, none of the builds have been able to update, Failure at 17% after the first reboot.
In real or virtual machine? In virtual machine it always fails. At 17% after the first restart. It is in hardware recognition that I am suspecting that it is precisely because it is a virtual machine (Hyper-V)
I upgraded the previous version to this one on actual hardware with zero problem (and very quickly, too, compared to the old days!)
