Hello Laszlo, could you please provide also a -doc package for the python3-grpcio package? Most of such package are named in the DPT in a way that the name for the additional package would be here python-grpcio-doc and contain the HTML documentation in the folder /usr/share/doc/$(package_name)/html For example https://packages.debian.org/sid/all/python-werkzeug-doc/filelist The advantage of such packages is we can use the object.inv files from these packages while building other -doc packages so we have a usefull interlinking between the documentations. This requires the other linked to packages are installed on the system of course. I will try to provide some patches or a MR to src:grpcio so the new package could be added more easily. The Sphinx based documentation can be found upstream here: https://github.com/grpc/grpc/tree/master/doc/python/sphinx Regards & Thanks Carsten PS: I'm sitting right now on preparing some Python OpenTelemetry packages and here python3-grpcio is needed as a binary dependency and the object.inv file from the documentation under https://grpc.github.io/grpc/python/ is used in the docu.
