Hi - Trying to install HACS and when I go to add the repository I get the following error:
'StoreManager.add_repository' blocked from execution, unsupported OS version
Installation method Home Assistant OS
Core 2026.3.4
Supervisor 2025.08.3
Operating System 11.5
Frontend 20260312.1
I can’t update more to the VERY latest as some of my integrations stop working so I rolled back. Any tips? Is it an OS update on my pi? I hope not as I’ve lost the HDMI adapter
