https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268407



--- Description ---
I'm using py39-certbot on 13.1Rp5 with pkg of latest repos.
I did 'pkg upgrade' and upgraded py39-acme from 1.31.0,1 to 2.0.0,1, and
py39-certbot cannot run with the following messages.

Traceback (most recent call last):
  File "/usr/local/bin/certbot", line 33, in <module>
    sys.exit(load_entry_point('certbot==1.31.0', 'console_scripts',

    return next(matches).load()

    from acme.client import ClientBase
ImportError: cannot import name 'ClientBase' from 'acme.client'

It works again by downdrading py39-acme from 2.0.0,1 to 1.31.0,1.
