由于 libssl 依赖，Debian 9.x 上的 apt-get install librdkafka1 失败 [英] `apt-get install librdkafka1` fails on Debian 9.x due to libssl dependency

问题描述

基本 apt-get install librdkafka1 在 Debian 8.x 上工作，但在 Debian 9.x 上失败.这看起来像是关于 libssl 的依赖版本问题.Debian 8.x 有 libssl1.0.0，而 Debian 9.x 有 libssl1.0.2 和 libssl1.1，但没有 libssl1.0.0，而且这个版本冲突只会导致 librdkafka1 安装中断.

Basic apt-get install librdkafka1 works on Debian 8.x but fails on Debian 9.x. This looks like a dependency version issue regarding libssl. Debian 8.x had libssl1.0.0 and Debian 9.x has libssl1.0.2 and libssl1.1, but no libssl1.0.0 and this version bump just causes the librdkafka1 install to break.

这很容易在最新的官方 Docker Debian 9 映像上重现:

This is easily reproducible on the latest official Docker Debian 9 image:

docker pull debian:9
docker run --rm -it debian:9

然后在虚拟机内

cat /etc/debian_version
# 9.4

apt-get update
# Get basics to setup Confluent repository
apt-get install -y wget gnupg2 software-properties-common libssl1.0.2

wget -qO - http://packages.confluent.io/deb/4.1/archive.key | apt-key add -
add-apt-repository "deb [arch=amd64] http://packages.confluent.io/deb/4.1 stable main"
apt-get update

apt-cache policy libssl1.0.2 结果:

libssl1.0.2:
  Installed: 1.0.2l-2+deb9u3
  Candidate: 1.0.2l-2+deb9u3
  Version table:
 *** 1.0.2l-2+deb9u3 500

     1.0.2l-2+deb9u2 500
        500 http://deb.debian.org/debian stretch/main amd64 Packages

apt-cache policy librdkafka1 结果:

librdkafka1:
  Installed: (none)
  Candidate: 0.11.4~1confluent4.1.0-1
  Version table:
     0.11.4~1confluent4.1.0-1 500
        500 http://packages.confluent.io/deb/4.1 stable/main amd64 Packages
     0.9.3-1 500
        500 http://deb.debian.org/debian stretch/main amd64 Packages

而 apt-get install librdkafka1 结果:

apt-cache search libssl 产生以下内容.请注意，有 libssl1.0.2 和 libssl1.1 但没有 libssl1.0.0

apt-cache search libssl produces the following. Note that there is a libssl1.0.2 and libssl1.1 but no libssl1.0.0

libssl-ocaml - OCaml bindings for OpenSSL (runtime)

更新:Confluent 4.1、librdkafka 0.11.4 和 Debian 9.4 仍然存在此问题.

UPDATE: This issue is still present with Confluent 4.1, librdkafka 0.11.4 and Debian 9.4.

推荐答案

librdkafka1 已添加到 stretch-backports:

librdkafka1 has been added to stretch-backports:

https://packages.debian.org/stretch-backports/librdkafka1

安装:

add-apt-repository "deb http://deb.debian.org/debian stretch-backports main contrib non-free"
apt-get update
apt-get install librdkafka1/stretch-backports

官方 Confluent repo 中的 librdkafka1 版本不支持 Debian 9.Confluent 平台本身从 Confluent 5.0 开始不正式支持 Debian 9:https://docs.confluent.io/current/installation/system-requirements.html#system-requirements

The version of librdkafka1 in the official Confluent repo doesn't support Debian 9. Confluent Platform itself doesn't officially support Debian 9 as of Confluent 5.0: https://docs.confluent.io/current/installation/system-requirements.html#system-requirements
