I have similar issues when updating from 2022.4.2 to 2022.4.7 and also when updating Unify addon from 2.1.0 to 2.1.1. Here’s the log from the unify update. Seems like an issue with ghcr.io
Same here, Using 2022.4.6 with latest stable updates (OS, Supervisor) Running it as an VM on ESXi.

Attempting to upgrade my HA running on Proxmox from core 2022.4.6 to 2022.4.7, but it sits there for a while saying installing, and then stops, then the install option presents itself again. Rebooted, tried again, same result. Is this a known issue at present?
