It is nice to see that there is instructions for Devuan at
https://certbot.eff.org/lets-encrypt/devuanascii-apache and that they
don't say to use snapd. However, what has certbot become?

I have yet to look at the source code, but there are a lot of dependencies:

The following NEW packages will be installed:
certbot python-certbot-apache python3-acme python3-augeas
python3-certbot python3-certbot-apache python3-cffi-backend
python3-configargparse
python3-configobj python3-cryptography python3-idna python3-josepy
python3-mock python3-openssl python3-parsedatetime python3-pbr
python3-pyasn1
python3-requests-toolbelt python3-rfc3339 python3-setuptools
python3-tz python3-zope.component python3-zope.event python3-zope.hookable
python3-zope.interface

Other than a manual install, are there any alternatives? I am interested
to hear how others are doing this.

Best regards,

Simon
