Thank you very much for your prompt reply Osiris.
I checked and the letsencrypt directory is in /etc as you say.
I did use certbot-auto.
If I have understood correctly it appears the path to certbot is only used again for setting up the auto-renewal of certificates so I will leave everything as-is.
You’ll end up with 99.9 % files which aren’t used if you’re just gonna use certbot-auto anyway. Just download that script and it’ll take care of the rest:
That’s the way I learned to do it when I first got started. It’s only 16Mb in size so not really an issue for most people. But thanks for the update to just getting the one script needed.
