Core Updates: Is there a "link" between x86 and Arm schedules?

I have two HASS installations: an x86-64 in the home and Raspberry Pi 4 in the Motorhome.
Up to recently, whenever there is an update for the x86 there is a complimentary update for the Pi.
But with the last three core updates for the x86 (2024.6.1-3/June7-15), there has not been a notification for the Pi?

The Pi seems to be able to access the internet - is there a repo that I need to check for?

All releases are built and released simultaneously. Generally the docker release might take an extra half hour, but it is built for all platforms and released at the same time using an automated build process in github.

Thank you. So I’ve now got to start figuring out why the Pi has stopped reporting that “updates are available”?
It was fine up to:

Any suggestions? Do you know the http: address that holds the update information?
