I'm slamming my head into a wall for not remembering archive.debian.org, *sigh*. For whatever reason, after digging through a huge stack of the current Debian project's site, I could only find dead links to wheezy packages. Dead links like
https://packages.debian.org/wheezy/iproute everywhere.
It's not that I want one of the koreader.debs -- I get that they won't work

, I've got the cervantes zip -- I just need one of the packages (iproute2) from ko-deps-latest.tar.gz in that thread, otherwise when koreader interacts with the wifi chip it crashes.
Thanks for pointing me to the archive, that's immensely helpful

. I'll report back once it's up and running.
