After receiving the email about this being invalid, I went to #ubuntu- bugs where this was discussed, however as seen by end of this log, I am stuck and I am leaving PC for tonight so I thought I should paste it here too.
``` 2015-07-28 18:30:34+0300 < 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 2015-07-28 18:30:34+0300 < 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 2015-07-28 18:30:34+0300 < Mikaela> What should I do? 2015-07-28 18:30:36+0300 < ubot5> Error: ubuntu bug 1479009 not found 2015-07-28 18:30:54+0300 < Mikaela> oh, yes, because it's marked as private, but I assume there is someone here who has access to it anyway 2015-07-28 18:34:01+0300 < TJ-> Mikaela: "#9 __memmove_ssse3 () at ../sysdeps/x86_64/multiarch/memcpy-ssse3.S:1384" 2015-07-28 18:35:25+0300 < Mikaela> that says nothing to me 2015-07-28 18:36:15+0300 < TJ-> Mikaela: it's the point in the stacktrace that appears to have caused the abort... I've seen that myself, too 2015-07-28 18:36:41+0300 < Mikaela> I see 2015-07-28 18:43:28+0300 < TJ-> It looks like the apport retracer has missed some debug symbol packages 2015-07-28 18:43:57+0300 < teward> or they weren't installed 2015-07-28 18:44:01+0300 < teward> therefore skipped 2015-07-28 18:45:06+0300 < TJ-> the retracer should install the relevant packages though 2015-07-28 18:46:23+0300 < 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 2015-07-28 18:47:12+0300 < TJ-> Mikaela: they're ddebs 2015-07-28 18:47:23+0300 < teward> TJ-: true... that's odd... 2015-07-28 18:47:42+0300 < TJ-> apt-cache search -n libxshmfence1-dbgsym 2015-07-28 18:47:42+0300 < TJ-> libxshmfence1-dbgsym - debug symbols for package libxshmfence1 2015-07-28 18:47:54+0300 < Mikaela> I am not sure what those are as I haven't heard that word earlier 2015-07-28 18:48:39+0300 < Mikaela> and that command returns nothing for me 2015-07-28 18:49:22+0300 < TJ-> I've checked there's no private info, and reassigned it public bug #1479009 2015-07-28 18:49:23+0300 < ubot5> bug 1479009 in xorg-server (Ubuntu) "Xorg crashed with SIGABRT when browsing aliexpress.com with Firefox" [Undecided,Invalid] https://launchpad.net/bugs/1479009 2015-07-28 18:49:39+0300 < TJ-> Mikaela: You'd need the ddebs repo in apt's sources 2015-07-28 18:50:55+0300 < Mikaela> I see. Should I find those somehow and then reproduce the bug and hope apport wants to send information again? 2015-07-28 18:54:01+0300 < 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 2015-07-28 18:54:04+0300 < TJ-> Mikaela: http://pastebin.ubuntu.com/11954239/ 2015-07-28 18:55:44+0300 < 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? 2015-07-28 18:56:14+0300 < TJ-> use the same bug report 2015-07-28 18:56:57+0300 < Mikaela> How? It always wants to open a new bug for me 2015-07-28 18:58:50+0300 < 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 2015-07-28 18:59:10+0300 < 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 2015-07-28 18:59:27+0300 < 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) 2015-07-28 19:00:03+0300 < TJ-> tarpman: Correct, but if the -dbgsym is installed locally the local apport will generate its own stacktrace 2015-07-28 19:00:17+0300 < tarpman> TJ-: neat, wasn't aware of that. 2015-07-28 19:00:23+0300 < TJ-> tarpman: version's match what is in the archive, too 2015-07-28 19:00:46+0300 < TJ-> tarpman: I seem to collect the -dbgsym packages and it helps a lot locally tracking down bugs 2015-07-28 19:01:00+0300 < Mikaela> I don't have proposed enabled, so I probably don't need to enable ddebs for it? 2015-07-28 19:05:46+0300 < TJ-> Mikaela: correct 2015-07-28 19:08:05+0300 <-- TJ- (~t...@jeeves.iam.tj) has quit (Quit: When did you last make another user feel special?) 2015-07-28 19:13:34+0300 < Mikaela> E: Unable to locate package libevdev2-dbgsym 2015-07-28 19:13:34+0300 < Mikaela> E: Unable to locate package libxshmfence1-dbgsym 2015-07-28 19:13:34+0300 < Mikaela> I have enabled the repository and "apt-cache search dbgsym" brings flood of results. ``` -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1479009 Title: Xorg crashed with SIGABRT when browsing aliexpress.com with Firefox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1479009/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
