The protoc compiler must be installed, currently version 3.21.12 is being used: https://github.com/protocolbuffers/protobuf/releases/tag/v21.12

The versioning is rather confusing, described here: https://protobuf.dev/support/version-support/

Most likely you want https://github.com/protocolbuffers/protobuf/releases/download/v21.12/protoc-21.12-linux-x86_64.zip

You can try to install from apt on Ubuntu, but you have no control on what exact version you are getting:

sudo apt install protobuf-compiler

Also install the following protoc plugins:

go install google.golang.org/protobuf/cmd/protoc-gen-go@v1.30.0
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@v1.3.0
go install github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-grpc-gateway@v2.18.0

In order to rebuild the protobuf interfaces, in case you make changes to any of the *.proto files, run make in this folder.
