Missing repository for an installed add-on

[SteveRMann]

I updated to Home Assistant OS 12.4 and the Samba Backup add-on is giving me this warning:

Missing repository for an installed add-on
Repository for add-on Samba Backup is missing. This means it will not get updates, and backups may not be restored correctly as the supervisor may not be able to build/download the resources required.

Please check the add-on’s documentation for installation instructions and add the repository to the store.

But, the repository is in the store.
I deleted the add-on and reinstalled, but the warning persists.

UPDATE - Rebooted the host and the warning went away.

I saw once in the past that custom addon repositories really got lost and had to be reconfigured. But if the repository is still listed on your system, it sounds more like a bug in the supervisor which "fixed" itself with a reboot.

I had to add repository back and reboot before it started working.
