I ran the command ./certbot-auto renew and it produced the output:
An unexpected error occurred:
ContextualVersionConflict: (rsa 4.5 (/opt/eff.org/certbot/venv/lib/python2.7/site-packages), Requirement.parse(‘rsa<4.1; python_version < “3”’), set([‘google-auth’]))
Please see the logfile ‘/tmp/tmpvGJndE/log’ for more details.
