EDIT: I know I can download and install manually, but my question is different and not a duplicate.

At my company we have a sand-box area where we have Debian machines. IT has white-listed *.debian.org to be able to install packages but this hasn't worked as some(many?most?) packages require a redirection to another domain.

In my case I'm currently trying to $ apt-get install rabbitmq-server and there's a list of about 30 .deb files that are blocked (dependencies). There will likely be other packages to install and test too, so the question is not specifically with rabbitmq.

Pestering IT to add to the white-list would be never ending (who knows what other domains we would need in the future, and IT probably doesn't want to continually growing the list).

I could go fetch the .deb files and install them manually, each one. But I'm concerned with the maintainability of this; I would have to repeat again instead of simply running $ apt-get update && apt-get upgrade. I've just stumbled on PPA (Personal Package Archive) am I on the right track or is there a better solution?

---- Edit: additional information ---

This is the type of error I'm getting

  • rabbitmq-server is in Debian, so you can install it with just downloads from debian.org. – Gilles 'SO- stop being evil' Jan 17 '17 at 0:01
  • It must be the dependencies that are not in debian.org then – Michael Jan 17 '17 at 0:02

    No, Debian is self-contained. All the dependencies of packages from Debian proper are in Debian proper. The only case where this wouldn't be true is if you've enabled third-party repositories that ship packages with the same name as packages from Debian proper, in which case, don't do that. Your question stands for packages that you do want to install and that you can't access directly, whatever they are, it's just that the example you gave isn't a good one. – Gilles 'SO- stop being evil' Jan 17 '17 at 0:04
  • Can you access the internet through a proxy? Most intranet setups allow this. – AlexP Jan 20 '17 at 21:17
  • Perhaps, but wouldn't this circumvent the white-listing that has been done. A classic example of "your users are your biggest IT risk" :P – Michael Jan 20 '17 at 22:02
