CLN: missing `python3-grpcio` dependency

[steepdawn974]

During install of the latest CLN 24.08.1 getting the (non fatal) error during the compilation phase: /usr/bin/python3: Error while finding module specification for 'grpc_tools.protoc' (ModuleNotFoundError: No module named 'grpc_tools')

According to the docs https://docs.corelightning.org/docs/installation the pip package python3-grpcio-tools is a dependency when building from source.

Proposed Solution: In build_sdcard.sh add the apt package python3-grpcio to python_dependencies.

This should solve it, but right now I don't have a test box to actually try it out and confirm, so I leave it as a bug report for now.

@openoms can you take a look

Please try to reinstall CLN with the updated cl.install.sh in the dev branch. Should cover all deps with poetry.

@openoms Hmm, that's what I had done... cl.update.sh reckless on dev (93777eda4d685b67ff4a812f1f3a3b87ca461c89) which does call cl.install.sh

But yes, if apt python3-grpcio needs to be added, then not in build_sdcard.sh as I suggested above but rather in cl.install.sh > installDependencies()

I went through the cl.* scripts again, and the CLN pyproject.toml , and yes, it should call poetry and poetry should install pyhton3-grpcio-tools as @openoms suggested..

Now that I have manually installed the apt package python3-grpcio on my blitz, I can't reproduce the old scenario anymore :(

When I find some time, I'll bring up a new blitz VM and test/confirm from scratch.

@openoms So should we add python3-grpcio here for v1.11.3 ? https://github.com/raspiblitz/raspiblitz/blob/93777eda4d685b67ff4a812f1f3a3b87ca461c89/home.admin/config.scripts/cl.install.sh#L35-L36

@rootzoll let's see if the error is there in the next rc image.

recovery on v1.11.3rc1 looking good:

₿ cat raspiblitz.provision-update.log | grep grpc
  - Installing grpcio (1.64.1)
  - Installing pyln-grpc-proto (0.1.2 /home/bitcoin/lightning/contrib/pyln-grpc-proto)
  - Installing grpcio-tools (1.62.2)
msggen cln-grpc/proto/node.proto

Perfect. Closing this for RaspiBlitz v1.11.3 release.
