Let’s Encryptの更新に失敗する

最近はこんな感じでLet’s Encryptの証明書の更新を更新しているのですが今回失敗しました.
(DocumenteRootをFQDNにしている前提)

$ sudo /bin/sh -c "/usr/bin/find /etc/letsencrypt/renewal/*.conf -type f | /usr/bin/xargs /usr/bin/basename -s .conf | xargs -n1 -I{} /usr/bin/letsencrypt renew --webroot -w /var/www/{}/ -d {}"

こんなふうに怒られます.
(仕様が変わった?)

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Currently, the renew verb is capable of either renewing all installed certificates that are due to be renewed or renewing a single certificate specified by its name. If you would like to renew specific certificates by their domains, use the certonly command. The renew verb may provide other options for selecting certificates to renew in the future.

とりあえずはletsencrypt renewletsencrypt certonlyにしたら通りました.

$ sudo /bin/sh -c "/usr/bin/find /etc/letsencrypt/renewal/*.conf -type f | /usr/bin/xargs /usr/bin/basename -s .conf | xargs -n1 -I{} /usr/bin/letsencrypt certonly --webroot -w /var/www/{}/ -d {}"

これで更新できたと思ったら1つのドメインで失敗しています.

   contain(s) the right IP address.

ファイルをDoumentRootに置いてLet’s Encryptからアクセスされるのですがそこでそのファイルが見つからないと失敗しています.このドメインはhttpを設定していませんでした.
てことでapacheでRewriteの設定をしてあげると

RewriteEngine On
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]

通りました.

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at

   will expire on 2018-05-31. To obtain a new or tweaked version of
   this certificate in the future, simply run certbot again. To

てことでbackportのものに入れ替え.

Description: automatically configure HTTPS using Let's Encrypt
 The objective of Certbot, Let's Encrypt, and the ACME (Automated
 Certificate Management Environment) protocol is to make it possible
 to set up an HTTPS server and have it automatically obtain a
 browser-trusted certificate, without any human intervention. This is
 accomplished by running a certificate management agent on the web
 server.
 .
 This agent is used to:
 .
   - Automatically prove to the Let's Encrypt CA that you control the website
   - Obtain a browser-trusted certificate and set it up on your web server
   - Keep track of when your certificate is going to expire, and renew it
   - Help you revoke the certificate if that ever becomes necessary.
 .
 This package contains the main application, including the standalone
 and the manual authenticators.

てことでclientが古かったのであまり参考になら無さそうなメモでした.
