How to Update Certbot

The TLS-SNI-01 validation is reaching end-of-life and this is forcing us to update our ACME clients to use an alternative validation method (either HTTP-01, DNS-01 or TLS-ALPN-01).

Not doing so, our certificate renewals will break and existing certificates will start to expire.

In order to handle this, here’s everything you need to do in order to update your Certbot client to a newer version:

wget https://dl.eff.org/certbot-auto && \
chmod a+x ./certbot-auto && \
./certbot-auto

That’s it! After the update your certificates will also be renewed.
