Trying to update. Problem, 2024.6.3 to 2024.6.4 not updating. Just does stuff, then reboots but still on 2023.6.3.
Anything in the logs, core and supervisor?
EDIT. And please, don’t be so sparse on information. What are you running, core, OS? And on what are you running this? The more information, the easier the help. 
Sorry, running HAOS on Intel NUC. No recent changes no problem updating to any previous update. Really posted figuring it was a common problem because I have a stable system, new hardware, no recent changes
Saw this in supervisor log:

Well that’s not good.
That’s a nice recovery though.
There are no breaking changes for the minor update so this is quite strange.
Have a look in config/home-assistant.log.1 to see what happened before the crash.
I think I am having same issue. What integration was causing this to crash?
