I installed Home Assistant OS 17.
I’m installing add-ons (MariaDB, Terminal & SSH) from the official add-on store.
When I make changes to the configuration and click Save, I get an error ‘Failed to save add-on configuration, Unknown error, see supervisor logs’.
I think this is a common issue affecting all add-ons in the system. It might be related to docker containers.
Please advise what I’m doing wrong?
(Additionally, I tried reinstalling Home Assistant OS and also tested version 15.2, but the problem persists.)
Please share the supervisor logs.
reboot and trying to configuring ‘Terminal & ssh’ add-on:
