----------------------------------------------------------------------- Debian Stable Updates Announcement SUA 174-1 https://www.debian.org debian-release@lists.debian.org Mattia Rizzolo November 6th, 2019 ----------------------------------------------------------------------- Package : dehydrated Version : 0.3.1-3+deb9u3 [stretch] Importance : high dehydrated is an implementation of the ACME protocol, as used by the Let's Encrypt certification authority to issue TLS certificates. The Let's Encrypt ACME endpoints have recently started to support the HTTP/2 protocol, which uses lower-case header field names. This leads to Dehydrated being unable to locate a required piece of information, and thus failures with the renewal or issuing of certificates. This update resolves the issue by using a case-insensitive search method. If you use dehydrated, we strongly recommend that you install this update. Upgrade Instructions -------------------- You can get the updated packages by adding the stable-updates archive for your distribution to your /etc/apt/sources.list: deb http://deb.debian.org/debian stretch-updates main deb-src http://deb.debian.org/debian stretch-updates main You can also use any of the Debian archive mirrors.
