When I use p4run to execute my p4 program, the system gives the above error and my protoc version is 3.6.1. can I find an older version of p4-utils to use the p4run command? Will it affect my p4 environment if I use the upgrade protobuf approach?

Use ubuntu 18

When I use ubuntu20, I have the same problem while my protubuf version is 3.18.3.

I solve this by modifying googleapis-common-protos == 1.52 in p4-utils/setup.py. The file looks like:

#!/usr/bin/env python3

"Setuptools params"

from setuptools import setup, find_packages

VERSION = '0.2'

modname = distname = 'p4utils'

def readme():

    with open('README.md','r') as f:
        return f.read()

setup(
    name=distname,
    version=VERSION,
    description='P4 language and bmv2 model utilities',
    author='Edgar Costa Molero',
    author_email='cedgar@ethz.ch',
    packages=find_packages(),
    long_description=readme(),
    entry_points={'console_scripts': ['p4run = p4utils.p4run:main']},
    include_package_data = True,
    classifiers=[
        "License :: OSI Approved :: BSD License",
        "Programming Language :: Python 3",
        "Development Status :: 2 - Pre-Alpha",
        "Intended Audience :: Developers",
        "Topic :: System :: Networking",
        ],
    keywords='networking p4 mininet',
    license='GPLv2',
    install_requires=[
        'googleapis-common-protos == 1.52',
        'grpcio >= 1.17.2',
        'ipaddr',
        'ipaddress',
        'networkx',
        'p4runtime',
        'protobuf == 3.18.3',
        'psutil',
        'scapy == 2.4.4',
        'setuptools',
    ],
    extras_require={}
)

And then try sudo ./install.sh again to install p4-utils.
