Current implementation of protobuf uses syntax of version 2 due to limitations regarding the version upgrade available through cross-rs.
The ubuntu version provided by the lib allows using version 3 but does not provide the latest versions of the protobuf-compiler.
It might be possible to compile and install on our own the latest version using the pre-build configuration of Cross but this will need a bit of work.
