| jibel | can anyone look at bug 1020574, last working desktop image was June 29th | 10:26 |
|---|---|---|
| ubot2 | Launchpad bug 1020574 in ubiquity "SystemError: Broken pipe while installing language packs" [Critical,Confirmed] https://launchpad.net/bugs/1020574 | 10:26 |
| cjwatson | jibel: xnox was looking at that yesterday | 10:31 |
| xnox | jibel: still working on it. | 10:32 |
| xnox | cjwatson: langpack installation suppose to catch and ignore SystemError, but for some reason sys.excepthook is called, after the SystemError has bubbledup in a loop.... | 10:33 |
| jibel | ok thanks. xnox I assigned the bug to you, so we know you're taking care of it. | 10:34 |
| cjwatson | distraction; the SystemError shouldn't be occurring here in the first place | 10:34 |
| xnox | cjwatson: then why the original code from ages ago has comment "ignore SystemError from langpack installation?" | 10:34 |
| xnox | ok | 10:34 |
| cjwatson | we didn't want random language pack failures to break the whole system; but that was more for things like package failed to unpack or something, not this sort of thing | 10:36 |
| xnox | ok | 10:36 |
| stgraber | xnox: can you easily reproduce that crash? if not, I have a pandaboard that's crashing every single time, so reproducing is easy here :) | 13:16 |
| xnox | stgraber: oh, it is reproducible every time with quantal daily since 29th in VM/desktop | 13:18 |
| stgraber | ok :) I only did arm installs recently, good to know any install will fail just as well :) | 13:18 |
| xnox | stgraber: so far my strace-foo didn't actually show me SIGPIPE, only the write("E: Broken Pipe") which comes from printing the stack trace in python, way to late. | 13:19 |
| xnox | stgraber: I can't wait to install my panda =) | 13:19 |
| xnox | stgraber: it's reproducible in a vm, which is what I am using now. | 13:19 |
| cjwatson | it might be EPIPE not SIGPIPE | 13:23 |
| cjwatson | in fact I'd say that's likely given that we're seeing several of them | 13:23 |
| xnox | cjwatson: not present in my strace either. I attached to the process just before clicking install now, cause otherwise the strace log was 300MB due to printing a line for almost each character of a debconf template fetch. | 13:24 |
| xnox | cjwatson: I am doing a full one by executing ubiquity under strace and logging into a separate hard-drive now. | 13:25 |
| xnox | also no obvious changes in python-apt nor ubiquity around the time. | 13:25 |
| cjwatson | apt and python-apt both had major changes at the relevant time | 13:38 |
| brendand | we have a bug with updating precise, which only happens when running the upgrade from a preseed: https://bugs.launchpad.net/checkbox-satellite/+bug/1021293 | 14:02 |
| ubot2 | Ubuntu bug 1021293 in checkbox-satellite "Ubuntu 12.04 install stalls when doing apt-get upgrade" [Undecided,New] | 14:02 |
| cjwatson | followed up | 14:06 |
| brendand | cjwatson, funny you ask. we've observed 'apt-get <defunct>' in ps | 14:20 |
| brendand | cjwatson, i'll ask the reporter to give full details though | 14:20 |
| cjwatson | yeah, I'm not going to get anything much out of one line | 14:20 |
| brendand | asap | 14:20 |
| roadmr | brendand, cjwatson: bug updated with the requested process list | 14:23 |
| cjwatson | hmph. | 14:26 |
| cjwatson | not obvious, will have to strace | 14:26 |
| cjwatson | brendand,roadmr: hm, worked for me in a normal session with strace attached | 14:55 |
| brendand | cjwatson, you mean without the preseed? | 14:55 |
| cjwatson | oh, admittedly I'm using a newer image | 14:55 |
| cjwatson | with the presee | 14:56 |
| cjwatson | d | 14:56 |
| brendand | cjwatson, a newer image - of precise? | 14:56 |
| cjwatson | yeah | 14:56 |
| xnox | brendand: there are daily precise images published with proposed enabled. | 14:56 |
| cjwatson | might be coincidental though and in any case wouldn't be a reason not to fix the underlying bug | 14:57 |
| cjwatson | probably just means I avoid some upgrade that triggers the bug, since it's already in the squashfs | 14:57 |
| brendand | xnox, details? | 14:57 |
| cjwatson | http://cdimage.ubuntu.com/precise/daily/ - but they aren't guaranteed, you shouldn't be relying on them for anything any more than you would rely on random daily builds | 14:58 |
| cjwatson | sorry, .../daily-live/ | 14:58 |
| brendand | cjwatson, right. interesting to know they are there though | 14:58 |
| brendand | cjwatson, it would be good to know if it reproduces for you using the release image. | 14:59 |
| cjwatson | I'm rsyncing back | 14:59 |
| brendand | cjwatson, by the way, this doesn't happen on servers | 14:59 |
| cjwatson | yeah, I know, not surprising at all | 15:00 |
| cjwatson | but not very helpful either TBH :) | 15:00 |
| cjwatson | different installer, so ... | 15:00 |
| cjwatson | (and ubiquity/success_command is already quite specific to ubiquity) | 15:01 |
| brendand | cjwatson, right - but the bug report is just to trim the symptoms down. the servers also use a preseed with the same steps - so the update is run in late_command | 15:02 |
| cjwatson | I know, and fair enough, but it's not a big help in this case | 15:03 |
| cjwatson | although granted, if a similar symptom had appeared on server, then it would probably have been quicker to diagnose there | 15:03 |
| brendand | cjwatson, if you need us to do anything, ping me or roadmr | 15:04 |
| cjwatson | ETA 40 mins or so for the image to arrive, so might not be today | 15:04 |
| mpt | I think ... I am going to suggest removing the big pictogram icons from the "Installation type" step | 15:52 |
| mpt | Partly to save space, and partly because they just aren't that expressive | 15:52 |
| mpt | (Saving space to make room for "[ ] Encrypt the new Ubuntu installation for security") | 15:52 |
| Blackyugin | Hi all, I work to ubiquity and I want to create my DBus witch connect to Ubuntu One. I see oneconf's DBusconnect and I need to know service's name. In oneconf is "com.ubuntu.OneConf". How I can know the Ubuntu One's name and all informations (hosts_object_name, package_set_interface, host_interface, etc.). Thanks a lot | 19:41 |
