Afaik the certbot-client doesn’t yet support automatic challenges with the dns-digitalocean authenticator. However, the certbot docker container does.

sudo docker run -it --rm --name certbot \
    -v "/etc/letsencrypt:/etc/letsencrypt" \
    "/var/lib/letsencrypt:/var/lib/letsencrypt" -v "<path-to-output-directory>:/keys" \
    certbot/dns-digitalocean certonly --server \
    --dns-digitalocean --dns-digitalocean-credentials <path-to-DO-conf.ini> "*.yourdomain.tld"

This worked for me:

Pretty simple actually.

sudo certbot certonly --server --manual --preferred-challenges dns -d *.<your.domain>

We’ll definitely be covering that topic! Quite a few of us here at DO were very excited to see this release. We’re looking into it now, but we’ll likely not provide a new tutorial until the new certbot version is available in the official PPA. See this convo on the Let’s Encrypt forum for more details:
