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='[email protected]',
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.

Based on the answer I have sovled the problem，thank you. My unbuntu version is 20.04，protobuf is 3.20.3
