'certbot.plugins.common' has no attribute 'TLSSNI01'

That sounds like a bit of a nuclear option to wipe my entire python package list. I looked it over and some seem important (ufw,fail2ban,PAM) and I don’t know what most of the others do. These few look like all that are related to certbot, would it be better to remove just these?

acme==0.40.0
certbot==1.0.0
certbot-apache==0.31.0
certbot-dns-cloudflare==1.0.0
cloudflare==2.3.1

Here is the whole list of packages that I have installed in case I missed any. I’d rather not just delete everything that’s installed.
