I am using letsencrypt for my server to support https. When looking around I find commands with certbot and others with certbot-auto with similar funcionalities. Do you need to use consistently one or the other? Can someone expalin the difference and in which case you would use each one?
If you use the certbot or letsencrypt command, you are using packages provided by your operating system vendor, which are often slow to update. If this is the case, you should probably switch to certbot-auto, which provides the latest version of Certbot on a variety of operating systems.
