Error returned from Supervisor: System is not ready with state: setup

Hi All,

Just updated my DEV(test) instance of HA running in a VM on proxmox server to core 2024.12.5 and OS version 14.1
It all seemed to be taking a very long time to restart so I looked at the console for this VM and saw this

Error returned from Supervisor: System is not ready with state: setup

Though I did find that after a while everything does seem to work

HA dashboards, SSH etc etc

So looks like some kind of timing issue!

running the ‘banner’ command brings up what I’d expect

My question is…
My Live HA instance is on a dedicated Dell OptiPlex mini PC. headless! so without connecting monitor how can I check before do any more updates to that?

Thanks

Hi

Why does this “banner” problem occur?
And how can it be prevented from happening again?

It’s happened few times to me, on different version, and now it happened again. It’s really annoying when all the home automation stops working, especially when I am not at home.

In my case, because I just had a bad addon (custom by me) that i was rebuilding in docker, and it failed, and i restarted HA manually, maybe something got corrupted not sure. And the only solutions, because the banner or anything did not work was to SSH into the console, then:

find the addons folder using ls command and then renamed the folder for the affected addon into something else.

Then Restarted HA, it worked.
