New install of HAOS on a RPI5 8GB with ZBT-1. Every time I try to install any integration (Thread, Matter, etc.) I get the above error.

Any idea what I'm doing wrong?

Installation method Home Assistant OS
Core 2026.2.1
Supervisor 2026.02.1
Operating System 17.1
Frontend 20260128.6

Can you install the Matter Server App manually before you try to install the Integration? Does that help?

#

This could be a bug in the dependency config (a regression due to going from Add-ons to Apps)
