ununtu 14.04 的 preference.d 不起作用，我做错了什么？

我已经在这里声明了 repo：

cat /etc/apt/sources.list.d/cloudera.list
# Packages for Cloudera's Distribution for Hadoop, Version 5, on Ubuntu 14.04 amd64
deb [arch=amd64] http://archive.cloudera.com/cdh5/ubuntu/trusty/amd64/cdh trusty-cdh5.3.3 contrib
deb-src http://archive.cloudera.com/cdh5/ubuntu/trusty/amd64/cdh trusty-cdh5.3.3 contrib

和偏好设置如下：

cat /etc/apt/preferences.d/cloudera.pref
Package: *
Pin: release o=Cloudera, l=Cloudera
Pin-Priority: 501

然后我有“问题”包。它应该从“Cloudera”存储库中获取。这就是使用首选项的原因。描述如下：http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cdh_ig_cdh5_install.html#topic_4_4_1_unique_2__section_dfx_p51_nj_unique_2

当我要求 apt 显示包 Origin 时，我发现它是从 Ubuntu 仓库获取的，而不是从 Cloudera 仓库获取的：

我做错了什么？

PS这可能是一个问题：

apt-cache showpkg zookeeper

看起来，由于首选项配置错误，zookeeper 并未从 Cloudera repo 中获取？

答案1

所以我已经清理了所有：

sudo apt-get --purge remove all_custom_packages

然后重新运行sudo apt-get install things-i-need 它就开始工作了。

这是命令的输出

apt-cache policy zookeeper
    zookeeper:
