ImportError: cannot import name 'cygrpc' from 'grpc._cython' (beta)

[ZephireNZ]

The problem

Multiple integrations are unable to setup in the latest beta:

• google_assistant_sdk
• nest
• google_generative_ai_conversation
• google_home (custom integration)

Looks like they're all trying to import cygrpc which is missing.

What version of Home Assistant Core has the issue?

core-2024.12.0b2

What was the last working version of Home Assistant Core?

core-2024.11.3 (but may have also worked on earlier beta builds)

What type of installation are you running?

Home Assistant Container

Integration causing the issue

google_assistant_sdk

Which architecture are you using?

[ZephireNZ]

x86 64-bit running in a container

[bdraco]

Where is /config/deps coming from?

[ZephireNZ]

From what I can tell, it looks to be the dependencies for HACS components. Clearing that off and having it re-populate seems to have resolved things 🤔

The grpc version in there before was 1.67.1 versus 1.66.2 after rebuilding from scratch. So potentially it was causing a conflict with the one that was being used by HA directly.

I'll close this off in that case, as it seems to be caused google_home custom component on upgrade.
