Ah juzo-kun, your Linux-tans have become the stuff of legend!
Today I needed to change apt sources on an Ubuntu server to point somewhere else, on account of an awry default mirror. Since Lucid, Ubuntu has supported the mirror method:
## /etc/apt/sources.list for Ubuntu 14.04 LTS ## Using mirror.txt pool for geographically-close servers deb mirror://mirrors.ubuntu.com/mirrors.txt trusty main restricted universe multiverse deb mirror://mirrors.ubuntu.com/mirrors.txt trusty-updates main restricted universe multiverse deb mirror://mirrors.ubuntu.com/mirrors.txt trusty-backports main restricted universe multiverse deb mirror://mirrors.ubuntu.com/mirrors.txt trusty-security main restricted universe multiverse
I was entirely unaware mirror had its own protocol! I’ll bet it’s reflective. Jokes aside, I swapped out my local mirror for these text files, and low and behold I was pulling packages from Optus. Half a day later, and it was iiNet.
Downloading the file directly (with http, not mirrors) resulted in this list:
http://mirror.optus.net/ubuntu/ http://ubuntu.mirror.serversaustralia.com.au/ubuntu/ http://mirror.netspace.net.au/pub/ubuntu/ http://ftp.iinet.net.au/pub/ubuntu/ http://mirror.overthewire.com.au/ubuntu/ http://ubuntu.mirror.crucial.com.au/ http://mirror.as24220.net/pub/ubuntu-archive/ http://mirror.internode.on.net/pub/ubuntu/ubuntu/ http://ubuntu.mirror.uber.com.au/archive/ http://mirror.as24220.net/pub/ubuntu/ http://mirror.aarnet.edu.au/pub/ubuntu/archive/ http://mirror.waia.asn.au/ubuntu/ http://archive.ubuntu.com/ubuntu/
An interesting approach. Rather than hitting the same repo each time, we’re given a pool of alternative, geographically-close servers.
