Michael Newton if this does not work there is also a force update you can do by doing this.
go to periodic folder >> then rename .htaccess to somthing like .htaccess.bak >> then go to your site in studio go to settings >> check the box force auto update even if some files where modified >> then go to this website https://www.yoursite.com/periodic/cron.php
i upgraded 4-5 times in a row this way to version B1 >> Rc1 >> Rc2 >> 10.0.0
the way to know it worked is if you get a white page after the white page stops loading your all good just refresh the dashboard within admin studio to see the new version now updated
also dont forget to rename .htaccess.bak back to .htaccess
MyZoid Vapour thanks for your input. I just manually run my cron via webmin.
LeonidS I did the changes manually and the site now states it is at version 10 but several modules will not install now. The other core modules did the update, as well as the updated version of the "points module" I just installed. But these in the photo will not install.
