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

问题描述

Basic apt-get install librdkafka1在Debian 8.x上有效，但在Debian 9.x上失败.这看起来像关于libssl的依赖版本问题. Debian 8.x具有libssl1.0.0，而Debian 9.x具有libssl1.0.2和libssl1.1，但是没有libssl1.0.0，并且此版本增加只会导致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.

这在最新的官方Docker Debian 9映像上很容易重现:

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VM中

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结果为:

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

apt-cache policy librdkafka1结果为:

librdkafka1:
  Installed: (none)
  Candidate: 0.11.4~1confluent4.1.0-1
  Version table:
     0.11.4~1confluent4.1.0-1 500

apt-get install librdkafka1结果为:

apt-cache search libssl产生以下内容.请注意，有一个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

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已添加到拉伸反向端口:

librdkafka1 has been added to stretch-backports:

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

要安装:

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

Confluent官方仓库中的librdkafka1版本不支持Debian9.从Confluent 5.0开始，Confluent Platform本身不正式支持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
