How can i fix this?

The command below helps
PROTOC_ZIP=protoc-3.7.1-linux-x86_64.zip
curl -OL https://github.com/google/protobuf/releases/download/v3.7.1/$PROTOC_ZIP
sudo unzip -o $PROTOC_ZIP -d /usr/local bin/protoc
sudo unzip -o $PROTOC_ZIP -d /usr/local include/*
rm -f $PROTOC_ZIP

@Rimay It looks like the latest protobuf https://github.com/protocolbuffers/protobuf/releases/download/v3.8.0/protoc-3.8.0-linux-x86_64.zip works as well.
