Hi Sir

Does it means I don’t need getting latest certbot version with backports ?

Thank you very much.


You should always aim to get the latest Certbot version, since there are other small bugs you may run into. We used to recommend installing the baseline OS distribution packages, but lately I’ve seen more and more people run into problems with outdated Certbot versions. My recommendation at this point would be to use certbot-auto, which will automatically keep itself up-to-date.

Hi Sir

Thank you very much, I’ll do it at once.
