I’m aware that armv7 (and therefore my Raspberry Pi 2 Model B) is unsupported with the upcoming release and that that means I can’t update my supervisor, but I don’t understand why that blocks me from installing add-ons on this still supported version of core-2025.11.3.

Any idea on how to get rid of the 'AddonManager.install' blocked from execution, system is not healthy - supervisor error?

And with a Pi2 which is also not supported it probably ran out of memory.

You should back-up to a set of mid-year HA versions that match and try that.
I mean you are now stuck at whatever rev forever, you should stick to a version that at least worked at one time.

Hey,

thanks for your reply.

The Pi consumes 300MB memory out of the 1GB memory it has. It should also be still supported with the version I’m running.

That’s a good idea and I was considering it, the thing that surprises me is that the system only became “unhealthy” and “unsupported” after the supervisor upgrade (as intended) failed. Now I can’t seem to get out of this state which in turn prohibits me from installing add-ons.

I too have still a Raspberry Pi 2B running. What I have see that a lot of add-ons have received updates lately that removed 32bits. So lastest versions can’t be installed anymore.

Did you try a host reboot, not just a HA restart?

Yes, unfortunately a full reboot and also disconnecting from power did not help. I’ll try with a fresh install where I don’t try to update the supervisor

Doesn’t work either, I might try downgrading to 15.2 later today and see if that does the trick.
