Perhaps is a bug, or i did something wrong, i updated from 6.1.16 to 6.1.22 from updates repo in Focal, but i had to download manually Extension Pack and Guest Additions ISO. If my memory doesnt fail, i had all the pack ( vbox + extension + guest additions) when updating previous versions of virtualbox in ubuntu.
