I got around this by just uninstalling the ubuntu protobuf-compiler and installing protobuf release directly from their github

PROTOC_VERSION=33.0
wget https://github.com/protocolbuffers/protobuf/releases/download/v${PROTOC_VERSION}/protoc-${PROTOC_VERSION}-linux-x86_64.zip

# Extract to /usr/local
sudo unzip -o protoc-${PROTOC_VERSION}-linux-x86_64.zip -d /usr/local bin/protoc
sudo unzip -o protoc-${PROTOC_VERSION}-linux-x86_64.zip -d /usr/local 'include/*'

sudo chmod +x /usr/local/bin/protoc

and I got further, we’ll see if there’s a problem later.
