| Mikaela | Hi, I am having trouble with Ubuntu 15.04 and Firefox. Always when I go to aliexpress.com and spend some time there, Xorg crashes and I am sent back to login screen (sddm). This has happened at least three times and only on the last time Apport succeeded at uploading backtrace and whatever it was doing. https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1479009 | 15:30 |
|---|---|---|
| ubot5 | Error: ubuntu bug 1479009 not found | 15:30 |
| Mikaela | Shortly after reporting that, Apport emailed me that my bug report is invalid, because my system is not up-to-date while it is and it complains about missing debug symbols for libevdev2 and libxshmfence1 as you can see. However there are no debug packages in Ubuntu repositories that I can see. My sources.lsit is http://sprunge.us/eNFQ | 15:30 |
| Mikaela | What should I do? | 15:30 |
| Mikaela | oh, yes, because it's marked as private, but I assume there is someone here who has access to it anyway | 15:30 |
| TJ- | Mikaela: "#9 __memmove_ssse3 () at ../sysdeps/x86_64/multiarch/memcpy-ssse3.S:1384" | 15:34 |
| Mikaela | that says nothing to me | 15:35 |
| TJ- | Mikaela: it's the point in the stacktrace that appears to have caused the abort... I've seen that myself, too | 15:36 |
| Mikaela | I see | 15:36 |
| TJ- | It looks like the apport retracer has missed some debug symbol packages | 15:43 |
| teward | or they weren't installed | 15:43 |
| teward | therefore skipped | 15:44 |
| TJ- | the retracer should install the relevant packages though | 15:45 |
| Mikaela | but those two packages don't exist, as far as I am aware they should be called as libevdev2-dbg and libxshmfence1-dbg, but if you apt-cache search without the -dbg you are only going to find those two packages, no dbg packages or anything else | 15:46 |
| TJ- | Mikaela: they're ddebs | 15:47 |
| teward | TJ-: true... that's odd... | 15:47 |
| TJ- | apt-cache search -n libxshmfence1-dbgsym | 15:47 |
| TJ- | libxshmfence1-dbgsym - debug symbols for package libxshmfence1 | 15:47 |
| Mikaela | I am not sure what those are as I haven't heard that word earlier | 15:47 |
| Mikaela | and that command returns nothing for me | 15:48 |
| TJ- | I've checked there's no private info, and reassigned it public bug #1479009 | 15:49 |
| ubot5 | bug 1479009 in xorg-server (Ubuntu) "Xorg crashed with SIGABRT when browsing aliexpress.com with Firefox" [Undecided,Invalid] https://launchpad.net/bugs/1479009 | 15:49 |
| TJ- | Mikaela: You'd need the ddebs repo in apt's sources | 15:49 |
| Mikaela | I see. Should I find those somehow and then reproduce the bug and hope apport wants to send information again? | 15:50 |
| TJ- | You might be able to capture a local stacktrace next time if you use them. This is my config (for trusty), amend it for vivid and the "apt-get update" then install the appropriate debug symbol packages that match the installed binary packages - debug packages end with -dbgsym | 15:54 |
| TJ- | Mikaela: http://pastebin.ubuntu.com/11954239/ | 15:54 |
| Mikaela | Thanks, I will take a look. What do I do when apport detects something, just open a new bug or can I tell it to send attachments to that one? | 15:55 |
| TJ- | use the same bug report | 15:56 |
| Mikaela | How? It always wants to open a new bug for me | 15:56 |
| tarpman | Mikaela: I could be wrong, but I don't believe "no debug symbol package found for libfoo" means you need to install the debug package on your own computer | 15:58 |
| tarpman | Mikaela: rather, the apport-retrace service (which runs off in the cloud somewhere) couldn't find a debug package matching the package and version you have installed | 15:59 |
| tarpman | Mikaela: hence the recommendation to check that those packages are up to date and come from the ubuntu archive (and not for example a ppa or such) | 15:59 |
| TJ- | tarpman: Correct, but if the -dbgsym is installed locally the local apport will generate its own stacktrace | 16:00 |
| tarpman | TJ-: neat, wasn't aware of that. | 16:00 |
| TJ- | tarpman: version's match what is in the archive, too | 16:00 |
| TJ- | tarpman: I seem to collect the -dbgsym packages and it helps a lot locally tracking down bugs | 16:00 |
| Mikaela | I don't have proposed enabled, so I probably don't need to enable ddebs for it? | 16:01 |
| TJ- | Mikaela: correct | 16:05 |
| Mikaela | E: Unable to locate package libevdev2-dbgsym | 16:13 |
| Mikaela | E: Unable to locate package libxshmfence1-dbgsym | 16:13 |
| Mikaela | I have enabled the repository and "apt-cache search dbgsym" brings flood of results. | 16:13 |
