Notes

Files

  • /etc/letsencrypt/
    • +archive/ - contains one folder per domain
      • +<domain folder>/ -- folder names are arbitrary, specified in renewal/ files
    • +live/
      • +<domain name> - contains links to the current files
    • +renewal/ - contains configurations to load (equivalent to sites-enabled/ in Apache/Nginx)

I'm guessing that LE adds a new fileset to archive/<domain folder>/ for each renewal, and updates the links in live/<domain name>.

Errors

  • Error requesting challenges: Error creating new authz :: Validations for new domains are disabled in the V1 API
    • This is because of the End of Life Plan for ACMEv1
    • If you've been using Let's Encrypt via VirtualMin, you may have to actually install CertBot (apparently VirtualMin has its own method of handling renewals but will use CertBot if it is installed) - instructions here, but basically:
      • apt install socat certbot
      • certbot register
