Question

基本apt-get install librdkafka1适用于Debian 8.x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，Debian 9.x有libssl1.0.2和libssl1.1，但没有libssl1.0.0，这个版本的爆发只会导致librdkafka1安装中断。

这在最新的官方Docker Debian 9图像上很容易重现：

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导致：

libssl1.0.2:
  Installed: 1.0.2l-2+deb9u3

apt-cache policy librdkafka1导致：

apt-get install librdkafka1导致：

更新：Confluent 4.1，librdkafka 0.11.4和Debian 9.4仍然存在此问题。

Answer 1

librdkafka1已添加到拉伸回传：

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

在Confluent官方仓库中librdkafka1的版本不支持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

Answer 2

仅供参考，主要的librdkafka维护者Edenhill在评论中回答了这个问题：

Confluent尚未为Debian 9提供librdkafka软件包，但是很快就会这样做。我建议你从源代码构建librdkafka直到然后，或检查标准的Debian软件包（最有可能有一个旧版本的librdkafka虽然）

librdkafka根本不支持Debian 9.从Confluent Platform 4.1开始，这仍然是正确的。 Debian 9仍然没有得到Confluent Platform的正式支持：https://docs.confluent.io/current/installation/installing_cp.html

Answer 3

我认为您的OtherActivity来源存在错误。

正如日志所说，存储库apt正在被使用并在Debian的存储库上提出新版本。

您可以使用packages.confluent.io或使用apt show python-kafka

的缓存查看包的相关性列表

您apt-cache show python-kafka从dist-upgrade到Jessie了吗？

由于libssl依赖，{apt-get install librdkafka1`在Debian 9.x上失败
