| * apw is doing a d-i server install and hitting 'Installation step failed' from 'Select and install software' ... where might i look for a log with what actually failed ? | 08:56 | |
| infinity | apw: syslog | 09:01 |
|---|---|---|
| cjwatson | and nano is the best viewer available, so 'nano -v /var/log/syslog' | 09:03 |
| apw | infinity, ta ... 'pkgsel' failed with error code 1 | 09:04 |
| apw | oh joy | 09:04 |
| cjwatson | no that's a consequential error, go up | 09:04 |
| cjwatson | it's no doubt some package or other failing to install | 09:04 |
| apw | looks like we also have a find before that, 'find: unrecongnised: -printf | 09:04 |
| cjwatson | can you copy out the full log for me? | 09:04 |
| cjwatson | 'anna-install openssh-client-udeb' gets you scp | 09:04 |
| apw | cjwatson, nice ... had to do that a few 1000 times i assume :) | 09:05 |
| infinity | I feel like I might be somewhat spoiled when I was about to complain that I was "only" getting 5MiB/s from github. | 09:06 |
| * apw slaps infinity ... somewhat | 09:06 | |
| cjwatson | apw: and implemented support for it ;-) | 09:06 |
| apw | cjwatson, for full disclosure i am tracking a bug here in the kernel, which i believe to be fixed which was blowing up the install before here. but it is possible i didn't do it right | 09:07 |
| apw | cjwatson, and this boot is of a | 09:07 |
| apw | cjwatson, and this boot is of an ISO that i have replaced the kernel in | 09:07 |
| infinity | apw: S'ok, all is right in the world, it scaled up to 9MiB/s now. | 09:07 |
| infinity | apw: You can stop feeling sorry for me. | 09:07 |
| apw | cjwatson, http://paste.ubuntu.com/5861037/ | 09:07 |
| apw | infinity, ok :) | 09:07 |
| apw | cjwatson, and in that log i would have hit 'return' to make it try again as well | 09:09 |
| apw | not deliberatly, but you know how focus grabby virtmanager is | 09:09 |
| cjwatson | what an interesting error | 09:11 |
| apw | cjwatson, i don't like the sounds of that ... :) | 09:12 |
| infinity | Since when does busybox provide dpkg? | 09:12 |
| cjwatson | we don't build that module | 09:12 |
| infinity | It thinks we do... | 09:13 |
| apw | Jul 10 08:52:49 in-target: dpkg: invalid option -- 'a' | 09:13 |
| apw | Jul 10 08:52:49 in-target: BusyBox v1.20.2 (Ubuntu 1:1.20.0-8ubuntu1) | 09:13 |
| apw | infinity, i assume that is what you are referring to | 09:14 |
| infinity | Indeed. | 09:14 |
| cjwatson | oh, only in static | 09:14 |
| cjwatson | wtf | 09:14 |
| apw | cjwatson, as this is a VM and the issue reproducible i can redo and get a cleaner log if that is any help | 09:14 |
| cjwatson | apw: I'm deeply confused, I think I need to see this in action - syncing an image for myself | 09:15 |
| cjwatson | busybox-static has been in installs for ages imo, dunno why this only just started breaking | 09:15 |
| cjwatson | busybox hasn't been changed for months | 09:15 |
| apw | cjwatson, ok now i am unsure if you can reproduce this or not at the moment as i have ended up here trying to find an issue which only hits with multi-lvm.preseed from the QA tests, and only then with 512M VMs | 09:16 |
| apw | cjwatson, and i have only seen this failure mode with the 'fixed' kernel as well, as without it oops in ext4 | 09:16 |
| apw | cjwatson, so i am somewhat worried i have made this happen and i am wasting your time | 09:16 |
| * apw fires up another VM with the original image | 09:17 | |
| cjwatson | so, busybox-static doesn't actually install the dpkg or find or whatever links | 09:18 |
| cjwatson | apw: do you still have the original vm running? | 09:18 |
| apw | cjwatson, sure do | 09:18 |
| cjwatson | the paths that might cause this kind of thing are in busybox's slightly tortuous "do I launch an applet or an external program" code | 09:18 |
| cjwatson | this is chrooted so that *should* be moot | 09:19 |
| cjwatson | 'chroot /target find --help' | 09:19 |
| cjwatson | does that give you the GNU findutils help, or something from busybox? | 09:19 |
| apw | busybox | 09:19 |
| apw | and /target is mounted off of --vg-root ... | 09:20 |
| cjwatson | apw: could you install strace in the installer environment ('udpkg -i /cdrom/pool/main/s/strace/strace_*.deb') and try stracing that? | 09:24 |
| cjwatson | and then copy out the strace for me | 09:24 |
| apw | stracing the chroot ? | 09:25 |
| cjwatson | Yeah | 09:25 |
| cjwatson | It's almost as if PREFER_APPLETS has got turned on | 09:25 |
| cjwatson | But I don't understand how that could have happened without changing busybox :) | 09:25 |
| cjwatson | Is this a self-built d-i initrd? | 09:26 |
| apw | cjwatson, it is hacked indeed, i have in theory only replaced the kernel and modules in it | 09:26 |
| apw | cjwatson, but i have opened and closed it, so i could easily be to blame | 09:26 |
| cjwatson | So I suspect you might have accidentally hacked a bit more than that | 09:26 |
| cjwatson | Let's see | 09:26 |
| cjwatson | What's the size of /bin/sh? | 09:26 |
| cjwatson | in the installer env | 09:26 |
| apw | 389928 | 09:27 |
| apw | http://paste.ubuntu.com/5861092/ | 09:28 |
| apw | cjwatson, ^^ | 09:28 |
| cjwatson | Looking | 09:32 |
| cjwatson | Is /bin/sh a symlink to /bin/busybox/ | 09:33 |
| cjwatson | ? | 09:33 |
| cjwatson | Actually maybe you could just put the initrd somewhere for me rather than me playing twenty-questions :) | 09:33 |
| cjwatson | busybox is following the ENABLE_FEATURE_PREFER_APPLETS path here, but I can't see why, since that's meant to be compiled out | 09:34 |
| apw | cjwatson, uploading now | 09:35 |
| apw | it is a big big, for various foolish error reasons on my behalf :) | 09:36 |
| apw | though for cirtain i am not replacing busybox or anything, deliberatly anyhow | 09:36 |
| apw | any my proceedure for replacement is cpio not using any tools | 09:37 |
| apw | cjwatson, http://people.canonical.com/~apw/misc/initrd.gz | 09:38 |
| cjwatson | cpio with what arguments? | 09:41 |
| apw | cpio --quiet --dereference -o -H newc | 09:42 |
| apw | stolen from mkinitramfs-tools sometime back | 09:42 |
| cjwatson | kill --dereference | 09:42 |
| cjwatson | that's almost certainly your problem | 09:42 |
| cjwatson | d-i does not build with that - it doesn't use initramfs-tools | 09:42 |
| apw | ahh ... great. i'll retest with that and let you kn | 09:42 |
| apw | know | 09:42 |
| apw | i knew it had to be me | 09:43 |
| cjwatson | not totally obvious why that broke it but it's the sort of thing that messes with busybox's delicate head :) | 09:43 |
| apw | heh ... that i can believe, thanks for all your help, infinity informs me i am doing this the hard way and is going to educate me | 09:44 |

| apw | cjwatson, hmmm if i did it right, that didn't help | 10:03 |
| cjwatson | OK, stick the new initrd up for me and I'll grab it | 10:04 |
| apw | i wonder if i extracted it in a way which already lost the links ... | 10:04 |
| cjwatson | That's possible. How did you extract it? | 10:05 |
| cjwatson | You might be better off building it using the proper d-i build system, assuming you already have the udebs. | 10:05 |
| cjwatson | I never unpack/rebuild d-i initrds by hand. | 10:05 |
| apw | zcat "$iso/install/initrd.gz" | ( cd initrd && sudo cpio -i ) | 10:06 |
| apw | cjwatson, i got into this because the isos i was originally changing were special ones used in QA and normal ones weren't triggering the error so i needed to debug that actual iso | 10:06 |
| apw | (this time round it is just how i am used to doing it now) | 10:07 |
| cjwatson | Might need --link, not sure. Like I say I don't normally do it that way | 10:08 |
| apw | cjwatson, yeah, i'll play some, now i know its likely my fault and compare the two | 10:09 |
| cjwatson | Normally I take debian-installer, make sure its kernel versions in build/config/ are right, put the modified udebs I'm using in build/localudebs/, and run 'fakeroot make -C rebuild_cdrom_isolinux' | 10:09 |
| cjwatson | er | 10:09 |
| cjwatson | 'fakeroot make -C build rebuild_cdrom_isolinux' | 10:09 |
| cjwatson | Other build targets are available - 'make -C build' on its own lists them | 10:09 |
| apw | yeah ... i'll also have that a spin | 10:10 |
| apw | it is about time i became more ohfay (sp?) with that | 10:10 |
| infinity | That would be the easier method I was suggesting. :) | 10:10 |
| infinity | Or, at least, more foolproof. | 10:10 |
| infinity | apw: And I have no idea what an ohfay is... | 10:11 |
| cjwatson | au fait | 10:15 |
| infinity | Oh. It's so cute when the English try to speak French. | 10:16 |
| infinity | Or, at least, spell it. | 10:16 |
| apw | i am renouned for my grasp of both spelling and foreign languages | 10:20 |
| apw | cjwatson, i am struggling to maek this di build (via make -C build) to use the localudebs, is there some magic i should be aware of | 12:10 |
| cjwatson | it should do it automatically | 12:11 |
| cjwatson | at least in cases where the same package name would have been used | 12:11 |
| cjwatson | is it a case of using the same package name but from the archive instead, or a case of trying to add an extra package? | 12:12 |
| apw | i am replacing all of the kernel udebs, it is building a Packages file | 12:13 |
| apw | which seems to list 'em just fine | 12:13 |
| apw | Package: kernel-image-3.10.0-2-generic-di | 12:14 |
| apw | Version: 3.10.0-2.10lp1195710v201307101138 | 12:14 |
| apw | and at versions above the archive | 12:14 |
| cjwatson | and does build/config/amd64.cfg have the right version? | 12:18 |
| cjwatson | (have to go out now) | 12:18 |
| apw | cjwatson, i'll check and hastle infinity :) | 12:19 |
| Riddell | cjwatson: could you verify this fix is done right? http://bazaar.launchpad.net/~ubuntu-core-dev/grub-installer/ubuntu/revision/1235 | 12:36 |
| apw | cjwatson, looking at the build logs it seems to be installing mine _and_ the ones from the archive, the latter last | 13:10 |
