preferences.d para o ununtu 14.04 não funciona, o que eu faço de errado?

Question

Eu repo declarou aqui:

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

e preferências aqui:

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

Então eu tenho o pacote "problema". Deve ser retirado do repo "Cloudera". Essa é a razão para usar preferências. Descrito aqui: link

Quando eu pergunto ao apt para me mostrar o pacote Origin, eu vejo que ele foi retirado do repositório do Ubuntu, não do repo da Cloudera:

O que eu faço de errado?

P.S. Pode ser um problema:

Parece que o zooneeper não foi retirado do repositório Cloudera devido a configurações incorretas?

    

Answer 1

Então, limpei tudo:

sudo apt-get --purge remove all_custom_packages

e, em seguida, reexecute sudo apt-get install things-i-need Começou a funcionar.

Aqui está a saída para o comando

apt-cache policy zookeeper
    zookeeper:
