[01:56] <zwelch> Hi all, I run a local ubuntu mirror of focal/jaunty, and my apt-mirror script decided today to (re-?)downloading 170GB of files.  Over a 20mbit connection no less.  Anyone know why this happened?
[02:13] <hloeung> zwelch, no idea, probably best switch to using `rsync` for mirroring?
[02:18] <zwelch> i know apt-mirror has been unmaintained for a long time; I have had to work out new patches with each of the past several LTS releases.  but does this mean that it's now officially recognized as broken/discouraged/unsupported?
[02:21] <hloeung> you're probably best asking in the Ubuntu support channel on whether `apt-mirror` is `broken/discouraged/unsupported`
[02:21] <hloeung> IIUC, it has always been encouraged to use `rsync` for mirror operators to keep their mirrors in sync with the main ones we operate
[02:22] <zwelch> incidentally, all of the files being downloaded are hosted on security.ubuntu.com
[02:23] <zwelch> I started mirroring a long long time ago, and I believe apt-mirror was the officially recommended tool to use.
[02:29] <hloeung> https://wiki.ubuntu.com/Mirrors?action=recall&rev=443 - this goes back to 2010
[02:29] <zwelch> i started mirror long before that :) 
[02:30] <hloeung> I honestly don't know how far back the recommendation to use `rsync` goes
[02:31] <hloeung> but yeah, not something we support
[02:31] <hloeung> anyways, I'll leave it here :)
[02:42] <zwelch> No worries.  It sounds like I just need to bite the bullet and switch to an rsync-based script.
[02:51] <zwelch> Looking at the ubumirror project, it looks like an rsync solution requires a full mirror of all active versions?  apt-mirror allowed me to only download the files for the distros that I'm using; is there an rsync-based solution that can do that?
[02:51] <zwelch> i.e. how do i mirror only those files required for focal/jaunty?
[19:26] <sarnold> zwelch: you can probably skip cloning security.ubuntu.com entirely, the usual archive mirrors get the security updates, too
[19:27] <sarnold> zwelch: the extra security.ubuntu.com is so people can get security updates more rapidly, in case their local country mirror syncs daily or weekly or something with a lot of extra latency
[20:01] <zwelch> sarnold: That's interesting.  How long has that been true?  Curious to know how long I've been downloading and storing security updates twice.... :)
[20:02] <maswan> hmm.. I think I remember this change being introduced, maybe around ubuntu 10-12 somewhere?
[20:03] <zwelch> i think i set up my mirror around 6 or 8, so "nearly the entire time"  :)
[20:08] <sarnold> zwelch: heh, that's a good question :) It's been this way since 2012 anyway
