| twb | So I'm trying to install via netboot. It doesn't ask me to set an http proxy (unlike Debian), and despite being told to use the internal mirror (an apt-cacher daemon), it's clear from the debugging log that it's trying to fetch .../Release directly from archive.ubuntu.com -- which doesn't work in my environment because http traffic that doesn't go through the proxy is dropped. | 05:42 |
|---|---|---|
| twb | Where .../Release is http://archive.ubuntu.com/ubuntu/dists/gutsy/Release | 05:50 |
| twb | What generates these files? http://archive.ubuntu.com/ubuntu/dists/gutsy/main/installer-i386/current/images/netboot/ubuntu-installer/i386/{linux,initrd.gz} | 10:46 |
| cjwatson | superm1: I don't think your r2181 is correct. apt-setup should take care of that already. | 10:53 |
| cjwatson | twb: part of the debian-installer source package build process | 10:54 |
| cjwatson | twb: we have a session scheduled for the next developer summit to fix a number of issues with networkless installation, which also covers this case | 10:54 |
| cjwatson | tepsipakki: erm, I forget whether this was one of the things that Anton already nacked ... | 10:54 |
| twb | cjwatson: well, I need to fix this bug NOW; before I start ripping apart the cpio, it occurred to me to investigate if there were already existing abstractions that could make the process less tedious. | 10:57 |
| cjwatson | twb: choose-mirror is hardcoded to go to archive.ubuntu.com to find out whether it needs to use a proxy, but that has a very short timeout | 10:58 |
| cjwatson | twb: can you post your preseed file, minus any sensitive information like passwords? | 10:59 |
| twb | I'm not using any preseed file yet | 10:59 |
| cjwatson | err | 10:59 |
| cjwatson | so how are you telling it to use the internal mirror? | 10:59 |
| twb | The problem is that here, any non-proxy web traffic is DROPPED | 10:59 |
| twb | Not rejected | 10:59 |
| cjwatson | I heard you | 10:59 |
| twb | So it's taking at least five minutes to time out before asking for a proxy | 10:59 |
| twb | By which time I give up | 10:59 |
| twb | I'm telling it to use the internal mirror by hand, when it asks which mirror to use | 11:00 |
| twb | I apologize if I'm being silly and thus sounding brash. | 11:01 |
| cjwatson | you can work around it using apt-setup/use_mirror=false and installing entirely from the CD | 11:02 |
| twb | I don't have a CD. | 11:02 |
| cjwatson | unfortunately that does mean you'll either have to set up sources.list to ... oh | 11:02 |
| tepsipakki | cjwatson: ah, so in that case debian won't be using it? I'll revert the commit then :) | 11:02 |
| cjwatson | tepsipakki: I didn't say that, I said I couldn't remember | 11:03 |
| cjwatson | tepsipakki: please don't revert it, I think Debian *should* be using it | 11:03 |
| tepsipakki | cjwatson: ok, I'll discuss it with gravity on FOSSCamp | 11:03 |
| cjwatson | tepsipakki: please grab me too :) | 11:04 |
| tepsipakki | maybe xsf could help getting this in d-i/console-setup | 11:04 |
| tepsipakki | cjwatson: sure :) | 11:04 |
| cjwatson | tepsipakki: oh, I have commit access, that's not a problem, I just need to refamiliarise myself with where Debian is in terms of console | 11:04 |
| cjwatson | twb: hmm, the case where you have a CD is the only one I know of where archive.ubuntu.com is hardcoded | 11:05 |
| cjwatson | twb: could I see your logs, please? | 11:05 |
| twb | Er, which log? | 11:05 |
| cjwatson | twb: syslog | 11:05 |
| tepsipakki | cjwatson: yep, but getting it acked would be easier if, say, xsf wanted to use it too :) | 11:05 |
| twb | Hmm... how can I get that off the system? The initrd doesn't contain ssh or scp | 11:05 |
| cjwatson | twb: nc | 11:07 |
| cjwatson | (and you can use 'anna-install openssh-client-udeb' to get scp, but only if it can talk to a mirror to retrieve it ...) | 11:07 |
| cjwatson | twb: or use the "save debug logs" item on the main menu | 11:08 |
| twb | menu? | 11:08 |
| cjwatson | back up ... | 11:08 |
| twb | OK, that menu | 11:08 |
| twb | The one you get when you click "Go Back" | 11:08 |
| cjwatson | correct | 11:09 |
| twb | Two more data: if I have the server tell (via DNS) the netboot client that "archive.ubuntu.com" --> 127.0.2.1, then it fails straightaway and immediately asks about the proxy; secondly, this issue occurs with both feisty and gutsy. | 11:14 |
| cjwatson | yes, it would | 11:18 |
| cjwatson | any luck on the logs? | 11:19 |
| twb | ftp://twb.ath.cx/tmp/syslog | 11:20 |
| cjwatson | hmm, of course, I misread that code path | 11:22 |
| cjwatson | bah, that code is so broken. There's really not much of a way around this in the existing code, short of something gross like replacing wget with a wrapper that just exits immediately if it's asked for something starting with http://archive.ubuntu.com/ | 11:26 |
| cjwatson | this code was one of the more desperate approaches to reducing the number of questions asked by d-i in the warty era. Now that we have ubiquity I'm very tempted to just rip it out. | 11:27 |
| twb | Please do. | 11:27 |
| twb | AFAICT it's simply wrong, and only ever worked by accident. | 11:27 |
| cjwatson | well, it makes a valiant attempt to avoid timeouts | 11:27 |
| cjwatson | but obviously not enough | 11:27 |
| cjwatson | it's not wrong *as such*, it's just very slow in some circumstances; in your case, I would be inclined to just preseed everything and not worry about the timeout because it could happen on all my machines in parallel and I could spend it having a cup of coffee | 11:28 |
| twb | It makes testing the preseed a horrible pain | 11:29 |
| cjwatson | that is not an attempt to argue that it isn't a bug, just that it shouldn't be a showstopper :) | 11:29 |
| twb | Shall I tell you the other problem? | 11:29 |
| cjwatson | sure | 11:29 |
| twb | 192.168.67.0/24 is a network just between the netboot server and the clients | 11:29 |
| twb | If I tell the client to use the proxy, which runs outside that NATted environment, then the proxy can't find the apt-cacher on 192.168.67.1 (for obvious reasons) | 11:31 |
| twb | But if I tell it NOT to use the proxy, er, something bad happens, I can't remember what. Lemme check | 11:31 |
| cjwatson | it doesn't sound like you should be telling it to use a proxy | 11:32 |
| cjwatson | while apt-cacher is a proxy in some sense it's acting more like a mirror here | 11:33 |
| twb | It's purpose is basically to reduce the download time because it's only going over the 100Mbit crossover, not the public internet | 11:33 |
| cjwatson | I understand, but that doesn't make it a proxy as far as d-i is concerned :) | 11:34 |
| twb | Oh no no no | 11:35 |
| twb | I'm telling it to use the squid proxy | 11:35 |
| cjwatson | it's a proxy if the requests are named for some host outside your network, but actually being sent to an internal host | 11:35 |
| cjwatson | doesn't sound like you can do both that and use the apt-cacher | 11:35 |
| twb | Right | 11:38 |
| twb | Essentially I want to set no_proxy=192.168.67.1 | 11:38 |
| cjwatson | but the proxy is *only* used to talk to the mirror | 11:38 |
| cjwatson | it's not used for any other purpose | 11:39 |
| twb | It's not used for security repo? | 11:39 |
| cjwatson | oh, yes, it is. you don't mirror that then? | 11:39 |
| twb | I could, but I can't TELL it to use my security mirror, AFAICT | 11:39 |
| cjwatson | you can, but only by preseeding | 11:39 |
| twb | Ah, OK.\ | 11:39 |
| cjwatson | apt-setup/security_host | 11:39 |
| twb | Where do you learn what these preseed keys are? | 11:39 |
| twb | For example, all the Debian documentation still talks about console-data/keymap instead of console-data-at/keymap | 11:40 |
| cjwatson | they're in the installation guide | 11:40 |
| cjwatson | https://help.ubuntu.com/7.04/installation-guide/i386/appendix-preseed.html | 11:40 |
| twb | Thanks. | 11:40 |
| cjwatson | I don't think there's a published version for 7.10 yet, but the differences are small | 11:41 |
| twb | It looks like a fork of the Debian Install Guide | 11:41 |
| cjwatson | it is | 11:41 |
| cjwatson | but with details adjusted, for example the one you pointed out above (except that it's not console-data-at/keymap either) | 11:42 |
| twb | Sorry, I may mis-remember | 11:42 |
| cjwatson | you'll want the console-setup/* questions for that | 11:42 |
| twb | Is that guide available as a PDF? | 11:44 |
| twb | html2ps doesn't appear able to cope with the https protocol. | 11:48 |
| cjwatson | yes, in the installation-guide-$ARCH package (e.g. installation-guide-i386) | 11:48 |
| twb | Thanks. | 11:49 |

| superm1 | cjwatson, that's why i have it in our branch only for now. It didn't seem sensible to me either that it was acting that way. I wasn't sure if apt-setup was missing something. Apparently it is, and mirrors aren't properly setup either. | 22:42 |
| superm1 | cjwatson, but in an effort to get our disk out i put that in | 22:42 |
