This question already has an answer here:

I'm on 64-bit Lubuntu 14.04 LTS. I keep the system fully updated by running apt-get update and apt-get dist-upgrade twice daily.

However, I notice that apt-get update "gets" both i386 and amd64 packages for nearly everything. For example:

Get:47 http://archive.ubuntu.com trusty/universe amd64 Packages [5,859 kB]

and

Get:51 http://archive.ubuntu.com trusty/universe i386 Packages [5,866 kB]

I've run dpkg -l | grep ":i386" but I just get back the prompt, indicating, I think, that I have no i386 packages installed.

My reason for asking is that if I could prevent the "getting" of i386 packages during apt-get update, I save my bandwidth and lessen the load, however marginally, on Canonical's servers.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • @muru, will running dpkg --remove-architecture i386 stop apt-get update from getting i386 packages? If so, I can delete my question. – DK Bose Dec 29 '15 at 17:19
  • It should. apt tried to get all supported architectures from repositories, unless you specifically state in sources.list that the repository should use a given architecture. Don't delete your question. Just mark it as a duplicate. – muru Dec 29 '15 at 17:21
  • @muru, Just one more clarification please... dpkg --add-architecture i386 will reverse dpkg -- remove -architecture i386? – DK Bose Dec 29 '15 at 17:24

    Yes, it should. – muru Dec 29 '15 at 17:25
