I’ve run update-upgrade commands, but still sitting on:
certbot 0.26.1
How do I upgrade the bot?
I got the email: Action required: Let’s Encrypt certificate renewals
You need to update your ACME client to use an alternative validation method
(HTTP-01, DNS-01 or TLS-ALPN-01) before this date or your certificate renewals
will break and existing certificates will start to expire.
